Hi everybody,
I took the GMAT last week and scored 760 (Q51, V41, IR8), I would like to thank this forum, especially the founder and Bunuel who wrote clear answers for all gmat quant questions.
I will share some elements of my experience, mystakes I did, and 5 take-aways, including:
- A study plan that could help several people to ‘secure’ score above 700 (I tried different preparation strategy and other people may benefit from it)
- How to get 51 in quant even if you’re not a math expert
My profile : After an undergrad in economics, I have been working in consulting in Europe for a few years.
Experience : PlanningMy preparation is also a bit unique as I tested 3 ways to prepare for the gmat.
MYSTAKE 1 - 2 WEEKS VERY INTENSE (2012) – I had taken the Gmat for my undergrad a few years before (700+ score) and thought that it would be quite easy to get a 700+ score again. I studied GMAT for 2,5 weeks : 10h x 15 days = 150 hours. After 2 weeks, I was scoring 680 on
MGMAT or 650 on a gmatprep and realized this was good but not enough. I discovered serveral people with 680 at
MGMAT could score 700+ but I felt it would be a bet. Some people prepare for 2-3 weeks and get 700+ but there is a high level of risk attached. I wanted an approach where I can ‘secure’ a 700+ score, not rely too much on chance.
After my trial in 2012, I had to put GMAT again on hold as I changed job. With hindsight, I should have continued but I thought I would resume later, this time working during a few months. My take-away is that it is not only a matter of hours (I had done around 150 hours within 2 weeks) but also length of study. To score high, the brain needs to be trained, solving exercise must become second-nature, sort of routine. 2 weeks is extremly short. My take-away was that it would be better to study 150 hours but over several months so that the brain would have time to digest all the learning.
MYSTAKE 2 – very light studies (5 hours / week - 2014) – 2 years later, having again more time thanks to a new job, I decided that I would resume studying but instead of studying hard during 3 months like most websites recommended, I decided I would just work once in a while, like 5-6 hours a week : 2 evenings x 1 hour, one afternoon in the week-end 3 hours. I thought this would let me the time to study for the gmat without changing at all my other activities (go out, see friends, etc… ). Sometimes, I had to stop completely for 2-3 weeks because of other activities.
After 4-5 months at this very low pace, I had completed the
MGMAT books, the
OG books and took some CAT tests. I thought I was ready for a high score, but scored around 650 (gmat prep). I realized that working a low number of hours every week led me to study quant over 2 months, then verbal over 2 months… but as it was very cool.
As I was learning, I was forgetting what I had learned a few weeks earlier. I should have learnt verbal while doing math exercise regularly to keep it fresh but with 5 hours / week I did not have time to do both
RIGHT APPROACH– FEW WEEKS AT GOOD PACE (12-16 hours / week) – In the end, I came back to the best approach : work 12-16 hours / week until my score in CAT would be satisfactory. I studied the past quarter. It is difficult to secure a high score without a certain intensity. I would recommend to study seriously and dive into it. I would study 3-4 days during workweek : Monday 1-2 hours (1h before dinner, 1h after) ; Tuesday : 1-2 hours, Wed : 1-2 hours ; no study Thursday and/or Friday ; 3-4 hours Saturday, 3-4 hours Sunday... (sometimes more)
It is important to continue to continue other activities while studying for GMAT. Continue to go out, see friends, do sport, relax, eat and sleep well. But it requires to be a bit more selective in your activities. I learnt a lot with Gmat about my priorities, studying Gmat allows to learn a lot about oneself. I would often study for periods of 1h - 1h30, have breaks of varying length....
- Material : I studied with
MGMAT (tried Kaplan but not as complete as
MGMAT). For people who want to strengthen verbal, I would recommend to replace the verbal books with
e-gmat. I noticed that I was scoring around 30 in verbal so I decided to take
e-gmat and definitely recommend it, I was key in my success in verbal. Thanks to
e-gmat, I improved from ~V30-33 to ~V40.
E-gmat takes some time (~100 hours for SC & CR) but helps to build confidence, which is crucial.
For Quant, I would recommend
GmatClub Tests. I read debrief of the people who score 51, most of them used
Gmatclub tests.
Gmatclub tests allowed me to go from 30% percentile to top 5% percentile.
I listened to a few sessions 'Thursday with Ron' and would recommend it. I listened a session on Reading Comprehension, Ron explanations are crystal clear on how to deal with a complicated RC passage (mainly focus on understanding the structure, like a table of content, don't bother too much about details).
- CAT : I tried
MGMAT, Veritas, Gmatprep but would recommend to use mainly Gmatprep. Gmat prep = 4 CAT x 2 times (do them twice) = 8 CAT.
MGMAT can be ok but I did not like much
MGMAT for 2 reasons : i) score is lower than actual gmat and this decreases confidence. ii) the scoring algorythm is not very close to the actual test. The actual test gives you questions from all difficulties whatever may be your level. If you score 5 questions correctly with
MGMAT,
MGMAT only gives you 700 level questions which take a long time to answer. In my view
MGMAT should adapt its algorythm and get closer to
Gmatclub tests (questions from all levels).
Test scoresVeritas (August) – 600 (Q40, V33)
GMAT PREP 1 (August) – 640 (Q47, V31)
GMAT PREP 2 (August) – 560 (Q49, V19) – I scored well in Quant but failed the verbal section
GMAT PREP 3 (Nov 1) – 650 (Q47, V33)
OFFICIAL CAT #1 (Nov 10) – 710 (Q47, V40) – I decided to retake since I could do better, in quant especially. After that, I mainly took
Gmatclub tests (10+ tests) which was crucial in my improvement.
GMAT PREP 1 (Dec 6) – retake – 750 (Q50, V41) – retaking was easier of course since I had done the test a few weeks before but allowed me to really understand how it feels to score high and finish all questions. It was very important for confidence.
GMAT PREP 2 (Dec 19) – retake - 730 (Q49, V40)
GMAT PREP 3 (Dec 20) – retake - 760 (Q51, V41) – This retake was really helpful to visualize what it meant to score 760, in terms of pace.
OFFICIAL CAT #2 – 760 (Q51, V41)
Test day experienceI took the test in the afternoon and would also recommend doing so for people who may have trouble going to bed early. The day before the test, I knew I may be a bit stressed. Having the test in the afternoon ensured I had enough sleep.
Essay and IR went pretty well.
On the quant part, I had the objective to do first 10 questions in 25 mn, then 20mn for 10 questions and finish a bit in a rush. I was actually ahead of schedule and completed the first 10 in less than 20 minutes. I finished the quant section with 2mn still on the clock. During the whole test, I was very often getting easy questions and really feared I had failed the first questions so that the software was giving me easy questions. This was the first time this was happening but this made me realize that most quant questions are from all level (500-600-700) and not only 700 as most people believe (see explanations below).
The verbal part was more difficult but I could still almost reach the end, I had to skip the last 2 questions (on CR).
5 key take-aways : errors I made, things I wish I knewTAKE-AWAY 1 : Gmat is not really adaptative. Or only 'slightly'I read a lot that Gmat is adaptatitve. If your answer is not correct, you get easier question. If your answers are correct 5 times in a row, you'll get harder questions,
it’s not true, or only partly. This is based on several observations. When I was retaking the Gmatprep CAT and scoring Q50 or Q51, I was answering most questions correctly and expected a strong increase in difficulty that didn’t occur. Getting Q51 is mainly solving a mix of 500, 600 and 700 level questions.
When scoring Q51, I analyzed the level of questions I had after having correctly answered the first 15 questions. The level was the following : level 600, then level 500, then 600, 600, one 700, again 600, 600, 500, 700, 700, 600, 600, 600… although I had all of them correct ! With the several Gmat prep software retake where I score Q50, it was always like that.
On the actual gmattest, it was also the same. The first 15 questions were mainly 600 level questions, some 600+, 1 or 2 were 700. Some could say that this feeling may be an imprsesion due to my training : I would view 700 questions as easy, but that is not the case. I know how a 700 question looks like and I would spend 3-4 minutes on several 700 questions of
gmatclub tests but for the real gmat, most of them could be done in 1mn 2mn max.
Q51 is not about solving 700 questions, it’s about solving questions from ALL LEVEL, from the first to the last question. Sorry to disappoint all the people who truly think the test is heavily adaptative.
In total for the actual test, I think I received a 700 level question (bit more tricky) EVERY 5-6 questions maybe. I was really surprised. I had heard all this time that GMAT is adaptative and gets really tough. I think it’s not the case. I think GMAT will ‘slightly’ adapt the level of questions. That is if you fail a lot of the first 10 questions, of course they will give you easier questions. But overall, it is not a huge impact. In my opinion, they give to ‘everyone’ a mix of questions from all level, you have to answer it.
When you think of it, what is GMAT looking for ? People who can answer a wide array of questions of varying difficulties. Gmat is interested if you can answer hard questions, but the software also wants to make sure you can answer easy questions. Because if you fail an easy question, Gmat can strongly decrease your score. Therefore, even for a quant genius, Gmat will throw 500 and 600 level questions all the way until question 37.
A final illustration of this are the Gmatclub prep tests, which are in my view the closest to test experience. Even if you get 10 times correct in a row, you’ll receive level 500, then level 600, 600, 600 700 and then again 600, 600…
In comparison,
Manhattan GMAT CAT thow only 700 level questions once you answer correctly. I don’t think
MGMAT closely represents how the algorithm works.
What are the impacts from that ?
1. Take
Gmatclub tests, whatever may be your initial level, you’ll work on a mix of questions from all levels that will best prepare you for the real test
2. It is more important to finish the test than to answer all of them correctly. It's like in high school, the teacher will give points to questions you answer. During several weeks, I would usually run out of time around the question 30 (verbal and quant), then I had to click any answer in the last 30 seconds. Many people say it but if you get stuck in a question, skip it, you’ll have 500 or 600 level question along the way and solving them can still allow you to score high in quant.
3. Don’t fear the level of question. To score Q51, you only need to answer correctly 6-7 tricky questions they will throw at you. For me it was the big take-away / surprise of these past weeks, confirmed by my test experience today.
4. To get Q51, don’t target to train only on 700 questions. It’s in my view more useful to work on all levels of questions and solve 500-600 level questions in 1 minute. As easy questions will constitute 80% of the questions. Once in a while, you get a tough question, then you can spend 4mn on it. Scoring high in quant doesn't mean solving so many 700 questions. I learnt this along the way.
Take-away 2: if you want to ‘secure’ a high score and start at ~500-600 level (like a lot of people) plan to study for 4-5 months or 250-300 hours (basic 3 months is in my view not relevant anymore to score high) In my opinion, the study plan for people who want to have a good score is 4-5 months or 250-300 hours. It’s something I wish I knew when I started. I read on this forum or in a lot of other forums that 3 months is a good time period. I think this is not relevant anymore, the norm will increasingly be 4-5 months for more and more people. 1 month Quant, 1 month Verbal, 1 month CAT = 3 months or 12 weeks x 15h / week = 180 hours. With less than 200 hours, you’ll have a good improvement (let’s say 50-70 points or from 620 to 680…), but not enough to score high.
- Genius and extremely brilliant people will of course succeed in 1 months or 2 (some in a few weeks) but this is a matter of probability.
- I read a lot of GMAT debriefs from the forum, I think a lot of people now study for 4-5 months rather than 3, and that the standard study plan suggested by Gmatclub on the forum (3 months) may be outdated. A lot of debriefs end of December talk about people that began to work during the summer, not in October. 80% of people with high score study more than 3 months, more like 4-5 months.
- Some debrief on the forum like ‘I am on Cloud 9; why you may ask; 760 - Q51, V41’ explain the person scored 760 with only 2 months preparation, but that was 2 months full time. Most people cannot afford that and do this in parallel of work. 2 months full time is maybe ~250-300 hours, which can only be achieved in 5 months if you work in parallel. Some debrief explain they scored 750 after a few weeks of work but this is for people who usually score above 650 in their diagnostic test.
- The Gmat added the Integrated Reasoning section. Although it’s not a huge load of work, it adds maybe 1-2 weeks (if you want let’s say to read a book on this, practice a bit).
- The level of GMAT has increased. I believe GMAC talked about it, and the percentile have evolved. In the past, you could study for 1-2 or 3 months and get a high score. I think it’s harder today. Study books have improved. At the time, you had only one book like Princeton review and you could land a 730. Now,
Manhattan Gmat only is 10 books. The average GMAT score for most programs has increased (sometimes +20-25 points since 2009).
=> Standard Gmat study plan is for me : 4-5 months
You find below a standard study plan I would recommend (to adapt depending on your strengths and weaknesses). This is a study plan for
- non US/UK test-takers (which means you have to work on Verbal) - if you grew up in US or UK, you may need less time for verbal
- people who have worked a few years (so maths and grammar skills are rusty and you need to go back to books and spend time learning content)
- people who are not particularly strong in quant (people with strong quant skills or engineers may take less time)
At the start, you may spend one week to understand the format and do your first practice CAT, you can :
- read the Math, Verbal and IR section of
the official guide and do a few questions (15 PS, 15 DS, 10 RC, 10 SC, 10 CR...) in order to get a feel for the test
- do a first practice CAT that will allow you to see your starting point but also your strengths and weaknesses (you may adapt the timeline below based on these). If you are already strong in quant, you may only need 2 weeks of training instead of 1,5 months..
I. QUANT : 1,5 months
1. THE CORE (reach Q40-47) – 4 weeks
a. Learning the content (2 weeks) – for instance read the 4-5
MGMAT books on Quant, or the Quant section of any book + exercises associated
b. Do
the Official guide Quant questions (2 weeks) – 400 questions on quant : maybe 10-15 hours to do the exercise, so double this time to do the correction, let’s say 2 weeks
2. AIM TOWARD Q47-51 –
gmatclub tests – 2 weeks
Do 10-15
GMat club tests (1h study + 1h30 review), that’s around 2 weeks.
II. VERBAL –-2 months
1. THE CORE (reach V30-37)
a. Learning the content (3 weeks), for instance 1 week on each book of
MGMAT (SC, CR, RC)
b. Practice
Official guide questions – 400 questions, let’s say around 2-3 weeks
2. AIM TOWARD V38-45 –
e-gmatPersonally, I would recommend replacing the books with
e-gmat (100 hours for SC + CR : ~ 5 weeks + practice
e-gmat questions in scholaranium : ~2 weeks)
So in total 5-7 weeks of
E-gmat +
OG questions (2 weeks), it’s around 7 to 9 weeks or ~2 months
III. BUILDING STAMINA 1,5 months
Finally, the key is to regularly do practice tests. Most study plan integrate around 1 months of training.
I would say 5-6 CAT may be enough if you already see a good score, but 10-12 CAT may be preferrable if you want to ‘secure’ a good score. One test is ~3h + 3h review or ~6 hours so that is ~60 hours or ~4 weeks.
Let’s keep a buffer of 2 weeks where you will retake some practice tests, review your
error log, or because you'll need more time than planned in a specific section. That means around 1,5 months of training.
In total, with this 5 months study plan (15 hours / week), I think the odds of landing a 700+ score are good.
Take-away 3 : use e-gmat for verbal and gmatclub tests for quant>
E-gmat is extremely useful and provides the base to aim toward 38-45
> Gmatclub provides the necessary training to score toward 49-51. I took 15
gmatclub tests. Gmat is not about being clever, it’s about practice, the more you practice, the more it becomes second nature. Some people already have a quant mindset (or work with figures at work), others don’t and need time to train this quant skill. When you do a gmatclub test every day (or every other day), it becomes just routine, just normal exercise, second nature.
Take-away 4 : for CAT Training, do GMAT prep TWICEI had read several debrief of people scoring 750-760, a common pattern was that several advised to take Gmatprep CAT twice. I did this and it really helped me a lot visualize what it meant to score 750-760. I mainly built confidence, which is key for test day. When you arrive at test day and have already scored 700+ on gmat prep several times, it brings a lot of confidence, which is key to succeed.
Take-away 5 : do not spend too long learning content, heavy practice is more important + review of error logI spent too long on
MGMAT books, reading carefully, making long notes, flash-cards on the concepts, on the
OG questions... In the end, of course it is key to write down the main concepts and formulas in the beginning, and do
the Official Guide. But the key is to practice. Clarity of concepts will only come through heavy practice. Before, I would spend a lot of time making flash-cards on specific concepts. With hindsight, the best thing was just to do 15
gmatclub tests in a row so 450 quant questions, then concept clarity gradually came.
Before, I would maintain an
error log without reviewing it a lot. On my road to Q51, I spent a whole afternoon reviewing my mystakes, writing how I could avoid them, how I would save time : I would recommend
1. An ‘
error log’ (paper-based in my case) : I didn’t keep an excel spreadsheet but wrote on paper I find it more convenient to review, add notes… When you’ll review something like 50-60 mystakes you did the day before the test, you’ll have in mind all possible mystakes which will considerably increase your accuracy, having all traps / tricks in mind. I found tiring to have to keep track everything on excel but it’s a personal choice
2. A ‘time log’ (paper-based in my case): I also wrote on paper the question which took me more than 3mn. I also redid these questions to achieve less than 1mn30. Sometime, I realized the question could be done in 1mn a certain way, I would write it down
Also, do not hesitate to read debrief of people who scored really high. In the beginning, I was targeting 710-720 and read mainly debriefs of people scoring 700-750. But after several months, I read debriefs of people who scored above 760 or 800. I would recommend to read these debriefs even if you target 650 or 700 since it will give you a sense of the pattern among good scorers, it can give you ideas.
2 improvement ideas for Gmatclub : 1. Have or hire a verbal moderator to do for Verbal what Bunuel did for Quant : a comprehensive explanation for all official Gmat questions
Thanks a lot to the founder of Gmatclub and Bunuel : his answers to official gmat questions are invaluable. When I was looking for explanation in quant, there was always Bunuel answer.
In comparison for Verbal, we have to search for a long time on google or forums to get a good answer and clean approach. Usually, I found a topic with everyone giving its point of view. Sometimes a moderator would contribute, but only to answer a specific question, rarely to provide an exhaustive answer (A – wrong because of … ; B ; wront because of …. ; C – correct because of ….).
Gmatclub took a great decision by hiring Bunuel and I think it would be great if you could do the same for the Verbal questions, that would be a huge improvement for future generations of test-takers.
2. Update of study plan
It may be necessary to udpate the "offline study plan" section of the forum post by founder BB : "GMAT Study Plan - How to Start your GMAT Prep". The 3 months study plan suggested seems to have been written in 2009 (more than 6 years ago) but still provides guidance to a lot of current test-takers.
As explained before, a note could be added at the end of this section to mention that 4-5 months may now be necessary, due to several evolutions: increases in level of gmat test takers over the past years, number of books by prep companies, average gmat required in school, integrated reasoning section added, or observation: a lot of Gmat debriefs with high score mention 4-5 months of study. In my view 3 months study plan may not be relevant anymore for majority of people.
As a side note, this raises the question in my opinion of the amount of work required for the Gmat. I think GMAC should simplify this exam that has become really heavy. Integrated reasoning section should be removed or merged with Quant section. I talked to people who prepared Gmat 10 years ago, you could score 750-770 with only 2 months preparation. Now, it looks like you need 4-6 months to secure such a high score.
Hope this debrief is useful to other people (sorry it is a bit long). Feel free to react to this post if you agree on some points (or not), or to send me a message if you have any question
