Hello all,
I have long lurked in the shadows of GMATClub, and learned much from fellow members. Now I would like to share my experience back with the community. Like many of you, I believe GMAT is one of those necessary evils that must be conquered one way or another. But one thing I've learned over the course of my preparation is that
GMAT is the one aspect of your MBA application that you can make the biggest improvement on given sufficient time and sweat. You can and will do well on the exam. Don't give up the fight!Background
A little bit of background on me. I graduated in 2010 and am currently working at an online marketing firm. I'm Chinese and came to the US during Middle School, and I've just recently gotten my US citizenship!

Anyways, enough about myself. Moving on to the more important stuff...
Quick Score Summary
Just a quick summary of my score and time that I took each exam. I had a pretty big gap between my two exams, but I didn't spend the whole time studying as I was suppose to. The actual amount of time I spent studying for each exam was surprisingly similar, but the quality of studying was very different and I'll explain more further down.

Study Materials
- The Official Guide to GMAT Review, 12th Edition
- Manhattan GMAT Sentence Correction
- Manhattan GMAT Critical Reasoning
- Manhattan GMAT Reading Comprehension
- PowerScore Critical Reasoning Bible
- Jeff Sackmann's Total GMAT Math
First, I want to give kudos to GMATClub, I based a lot of my purchase decisions on the book reviews I read in the forums. Among these study materials, the ones that I personally found most useful are:
The Official Guide to GMAT Review, 12th Edition - the only source of legit GMAT problems, you can't ask for better practice problems than these.
Manhattan GMAT Sentence Correction - IMHO, the go-to book for sentence correction. This + doing additional practice problems (the book unfortunately lacks them) will get you very far.
PowerScore Critical Reasoning Bible - This book is quite dense, and I had a hard time understanding some of the strategies mentioned. But this is a very decent book on the subject matter and I would recommend it to you if you want to improve in this topic.
Jeff Sackmann's Total GMAT Math - This is a great and concise overview of all math concepts tested on the GMAT + sizable number of practice problems. My only complaint is that it contains quite a bit of typos that led me to pull on my hair on multiple occasions.
Online Course
Knewton GMATI took Knewton's online course after receiving my unsatisfying score on my first GMAT exam, and did not regret the decision a single bit. I understand that there are dozens of different online courses out there and there's no way I could make valid comparisons since I never took the other ones. However, just from experience, I really
liked the Knewton course. It is well paced and effective organized, the pre-recorded videos are top-notch, and the instructors are funny and smart at the same time. In fact, I would thank those instructors personally, they made GMAT... much more interesting (and that isn't something easy to pull off for test prep). *hats off*. I understand this comes down more to personal preference. There are a lot of different classes (online, on-demand, or on-site) available, I would urge you to do some research to find the one most suitable for you. Oh, and GMATClub members get discounts.
GMATClub Resources
Error Log by Spoilt - this is my favorite
error log out of all because it is simple enough to use and provide sufficient statistic on how well you do in each section and for each type of the question type (very useful for identifying weaknesses). I used this to analyze my result on the GMATPrep software.
Guide to Perfect 6.0 AWA GMAT Score - Whoever wrote this has my greatest thanks. This is a very well written guide for AWA on the exam. I created my own AWA cheat sheet based on this and it has served me very well. For AWA, I think strcuture and organization > content in most cases. So read this, create your own version in your head, and the rest will be history.
GMAT Club's GMAT Flashcards - this is a pretty well-made compilation considering that it's a community project. I used this for a quick review a few weeks before my second GMAT, and learned a few tricks for some Quant questions.
GMATClub Tests - I got these tests for FREE after signning up for Knewton. Unfortunately I didn't get to use most of them regrettably. There are lots of Quant problems for practice, and more practice is always good!
The First GMAT
Preparation Time ~ 3 months
I started preparing for my GMAT after a lot of procrastination in 2011. I had all the book materials sitting in a pile on my desk untouched for at least a month, up until July, when I finally started going through them one-by-one. What didn't help was the fact that I did not have a very consistent schedule either. I just did everything at my own pace, skip studying altogether if I felt tired, and plodded on slowly for 2 months.
By the end of the 2 months, I chewed through most of the book material I had. However, I could not comment on how much I actually retained. In the last month I divided my attention between reviewing more verbal (my weakness) strategies and taking practice exams.
MGMAT CAT 1 - 600
MGMAT CAT 2 - 710
MGMAT CAT 3 - 600
MGMAT CAT 4 - 670
GMATPrep CAT 1 - 640
GMATPrep CAT 2 - 660
I may have the wrong scores for GMATPrep since the stupid software (before they made the pretty graphic update) only showed you the score page once and never again. A quick comment on the above scores. Yes, they're pretty mediocre and all over the board. I didn't read too much into the scores back then.
And then I took the exam in early October
| Month | Verbal | Quant | Total | Analytical Writing |
| 2011/10 | 29 | 48 | 640 | 6.0 |
Wow, was I disappointed to see my score in that testing room. That feeling of dejection wasn't something I could shake off for the rest of the week. But upon closer inspection, I told myself that this is the score I deserved because I really haven't put in much effort. The fight isn't over and I need to train well to win the next one.
The Interim
Not soon after my exam, work ramped up for the holiday season (gotta love marketing!) and then came the holidays, presents, and small vacations... Needless to say, I took a long break from GMAT. The break was both good and bad. It was good because I was able to forget about my miserable experience on the first GMAT. It was bad because I pretty much forgot everything I learned.
The Second GMAT
Preparation Time ~ 3 months
In a blink of an eye, 2011 ended and 2012 sneaked up on me - the Year of the Dragon! I did try to get back into GMAT a few times after my first exam, but I never followed through due to the lack of motivation. However, 2012 is different for some reason, I suddenly had a renewed urge to beat the GMAT. Perhaps some stars have aligned for the first time in a century, perhaps the Year of the Dragon, an auspicious year for ambitious undertakings, has spoken to my inner desire. This time, I told myself, I will fight GMAT and win.
Learning from my earlier mistakes, I know that motivation can be a fickle thing. I need something else to push me along, to keep me on a schedule. This is where Knewton comes in. I watched a few videos from Knewton through GMATClub and really liked the presentation style, and after checking their website, I find it a suitable choice for me (e.g. organized course plan, witty instructors, good number of practice problems). Just like that, I signed up for the On-Demand course in January and began my second battle.
Thanks to my score report from the first GMAT, I knew I needed to concentrate on verbal since I have the most to gain on that section. Knewton kept me busy and on schedule. While my focus was on verbal, one other thing occupied me - timing. I cannot stress how important timing is on the GMAT. On my first GMAT, not only did I run out of time toward the end of both sections and had to guess, I actually ran out of time guessing... That's right, folks. I literally SKIPPED problems (I can imagine the horror on everyone's face upon hearing that word). You get heavily penalized for not completing the exam. So please do complete it when you take it, for my sake.

One of the best ways to improve your timing is to get in the habit of timing yourself for practice problems. Use any tool you feel comfortable using, time yourself for a set of 5 problems (~10min), 10 problems (~20min), and 20 problems (~40min). The estimated time I used earlier was for the Quantitative section, Verbal questions are a little different and require different amount of times (e.g. SC should be ~1.5min, CR ~2min, RC ~1.5min not counting the passage)
After 2 months of focusing on Verbal and Timing, I significantly improved my verbal score and timing on the verbal section (no surprise at the correlation there).
Below are my practice exam scores:
Knewton CAT 1 - 640
Knewton CAT 2 - 680
Knewton CAT 3 - 570
Knewton CAT 4 - 570
Knewton CAT 5 - 640
MGMAT CAT 1 - 710
MGMAT CAT 2 - 720
MGMAT CAT 3 - 700
MGMAT CAT 4 - 710
MGMAT CAT 5 - 720
GMATPrep CAT 1 - 710
GMATPrep CAT 2 - 680 (new software)
GMATPrep CAT 3 - 710 (new software)
Let me explain a little about the scores above. Knewton CATs, in my opinion, is one of the biggest weakness of the course. First of all, I don't think the scoring algorithm is very accurate. Second, the questions themselves can be awkward and a little confusing at times. I did poorly on the exams as you can see. The scores didn't mean too much for me though, because I only care about the wrong answers.
When I started doing the
MGMAT CATs again, I feel a bit more assured about the consistency. But once again, the scores mattered less. What's more important are the lessons that I can learn from the mistakes I made!
Between the practice exams and additional practice problems from Knewton and book materials, I felt more comfortable about doing each type of problems. Before, if I see an unfamiliar question I would panic and not know what to do next. Now, I can identify the approach systematically (most of the time at least). Practice makes perfect, remember that.
I took my 2nd GMAT exam in the afternoon at ~3pm, versus the 1st exam, which I took it in the morning at 8am. I think the new exam time was a positive change for me since I'm never really a morning person. The exam was on a weekday, so I took the entire day off. I selpt in that morning, woke up at 9. Took a long shower and ate a full breakfast. The rest of the morning I spent reading over my notes, watching some Hulu, and played a little video game (helped me destress a bit). I ate lunch at 12 and immeidately took a 30min nap shotly after ( I knew that if I didn't take this nap, I would get very tired in the late afternoon). At ~2 I headed to the test center.
The test center was different on a weekday vs. on a weekend. There were fewer people at the center than there were my first time, and nobody was in the waiting room. I arrived 30min early and they got me started right away. The essays were not difficult, I had fun writing them, and that went on smoothly for an hour.
Next came the Quant section. For me, the biggest stumbling block is accurately translating word problems into equations, I have a tendency of missing details or misintepretating the problem altogether (hence, I sometimes panic when I see long word problems). Quant is also the section that I still had trouble controling my timing (on my CATs, I always run very close on Quant). The first 10 questions felt alright, I didn't have much problem, then out of no where long word problems start appearing and I find myself rereading them more times than I should. For the rest of the section I encountered several problems that I wasn't sure if my apporach was correct. But I moved on anyways, because I knew that spending too long on a problem does not guarantee getting it right, and it takes away precious time from problems that you can get right. At the end, I was cutting it clsoe again, with less than a minute left. I did guess the second to last question. I didn't feel too good about that. But Quant was over, there was no need to think about it longer.
It is the Verbal section that my test prep paid off the most. I say that because I was able to go from guessing the last 6-7 questions on the 1st GMAT to finishing the section with ~15min left on the 2nd GMAT. I just wanted to put that out now because strategy + practices on Verbal definitely made a huge difference here. Despite the score, thinking back, I didn't feel good about the Verbal section while doing it. On multiple occasions, I ended up with two likely anwer choices and couldn't decide between them. It drove me a bit crazy, but there was nothing I could do. I made my 50/50 guess and moved on. Overall, the questions on the Verbal did not feel too difficult compared to the practice problems I've done. By the time I finished the section, those 50/50 guesses I made really made me nervous.
Given what I've been getting on the CATs, I was hoping for a 710, but I surprised even myself when I saw the score screen at the end of my second GMAT:
| Month | Verbal | Quant | Total | Analytical Writing |
| 2012/04 | 46 | 49 | 760 | N/A |
Was it luck? Perhaps. The Year of Dragon? Maybe. But I think what helped me beat GMAT was the collection of mistakes I made along the way and the lessons I learned from them.
Take-Aways
1. You CAN make big improvements on GMAT, and I mean BIG improvements.
2. Keep to a schedule as best as you can.
3. Focus on your weak areas if you've identified them. Because they will help you gain the most.
4. Don't underestimate timing on the exam. Be comfortable with the pace.
5. Focus on the mistakes you made on CATs rather than the scores. Because you will get HIGHER scores if you learn from your mistakes.
6. If you feel that you can benefit from a course (on-demand, online, or on-site), find one that suits your needs and DO it.
7. Get motivated, GMATClub is a great source of motivation. Feel free to lurk around
or come out and say hi.Okay, time for me to take a break from typing.

If you have any question for me, ask away.
