610 to 760 (Q50, V41) - GMAT experience and advice

Question

Greetings, GMAT warriors

I took the GMAT this morning so for those who are interested, here is a brief rundown of my GMAT experience, along with some tips for those of you studying for the exam.

Short overview of studies with some highlights 
I started my studies in August, with the exam planned for December, so I had 3-4 months of studies. I wouldn't recommend dragging it out any further, because at the end I was quite burned out. I didn't buy any of the prep courses offered by MGMAT, Veritas etc, mainly because I didn't think I'd get much use out of them. I know they can be a big help for others though, especially because of the diagnostics tools they offer, which help find the areas where your knowledge is lacking. If you think something like that would help you in your studies, then definitely go for it.

At first I studied using only the OG, but it quickly turned out to be very lacking in terms of strategy. My first 3 CATs (as shown below) were done after having mostly studied using the OG, producing not too high scores. I then discovered the MGMAT guides, and boy were they good. I started using them sometime around my first Veritas CAT and I suppose the score on my GMATPrep CAT 2 reflects the improvement from studying the MGMAT guides. Speaking of the first GMATPrep CAT, I would highly recommend anyone attempting them to watch their fingers and to stay away from the CTRL-W (close tab) shortcut. For some inexplicable reason, the software doesn't save your progress if you close the tab, so unless you want to spend a whole morning preparing for the CAT and perform better than ever only to have it all erased 3 hours in, like I did, then keep your fingers in check! Also, the GMATPrep CAT 2 was written around 30 minutes after the first one was interrupted, because I didn't want to finish the day with nothing to show for it. Needless to say I didn't expect the score I got, and MGMAT deserves a lot of praise for their guides.

Towards the end of my prep, I had gone through most of the MGMAT books and only really needed a lot of practice questions. For this, the GMAT Club forum question bank was very useful. However, GMAT Club also has a lot of garbage questions that in no way reflect what you would actually encounter on the exam. I set up the filter to only get questions from GMAC, MGMAT, Veritas and the Economist, and I'd recommend you do something similar.

The day before the exam, I laid out all the items and clothes I would need, so I wouldn't have to look for anything when I woke up. My appointment was scheduled for 9 AM, so I went to bed at 8 PM, got about 10 hours of sleep, and got up at 6 AM, ate breakfast and took a cold shower to help wake my brain up. To no surpise, the exam itself ended up being very similar to the official GMATPrep CATs, both in terms of questions and user interface, so it helps to have done a few of them in advance.

Practice materials used 
 MGMAT quant, RC & SC guides.  These were absolutely essential for learning the strategies necessary to beat especially quant and reading comprehension. Highlights for the quant books include the following:
 Guide 1 
 
 Ratios - This is quite a short chapter, but despite being one of my harder areas at first, MGMAT made these questions very trivial to solve  
 Guide 2 
 
 Quadratic equations - F.e. knowing how to easily derive a and b in the format  (x+y)(x+z)=X^2+ax+b  is very useful, especially for data sufficiency questions 
 Inequalities - These used to mess me up all the time at first, but with MGMAT they eventually became trivial.  
 Guide 3 
 
 The double matrix method for overlapping sets - This was by far one of the most useful strategies I took away from the MGMAT guides. Very intuitive method for solving not only overlapping sets, but also some probability questions (eg. "what's the probability of both events A and B occuring?") 
 The RTD (rate-time-distance)/RTW (rate-time-work) chart for solving work rate problems - Makes it much easier to solve these problems. Also goes very quick to write out once you've done a few of these questions. My system would be to always draw 3 vertical lines and 3 horizontal lines and start filling out the chart in exactly the same way every time. This way I never had to think about how to approach a work rate problem. 
 Consecutive integers - These are tested quite often, and MGMAT does quite a good job in explaining it all.  
 Guide 4 
 
 Ratios of side lengths of 30-60-90 triangles and 45-45-90 triangles - Very good to know especially for data sufficiency questions.  
 Guide 5 
 
 Combinations - Very intuitive and easy-to-remember methods for solving these problems 
 Properties of primes and prime factors - Seriously, these show up all the time on the GMAT, so learning this stuff is very helpful. MGMAT explains it all quite well.  
 OG 2019.  The OG was very useful for me, but only for one purpose. Being the  official  guide, the practice questions are good to go through at least once. The easy questions are  very  easy though, and I'd only recommend the medium and hard questions. However, the explanations provided by GMAC on the quant section are often completely useless, and include zero strategy. The methods provided are often ones that you would never want to use on the actual exam.

Economist free CAT.  Very good for getting a first taste of the GMAT and getting familiar with the test format and types of questions that show up.

Veritas Prep free CATs.  These mock tests are included with your free GMAT Club membership and were was similar enough to the real GMAT experience, but did have some weird quant questions from time to time. Since you get two tests, you can measure whether you're improving. You shouldn't compare these scores with the official mock tests scores though.

MGMAT free CAT.  As with the Veritas mock tests, this is pretty similar to the official mocks. As is pretty much common knowledge by now, the quant section is quite a bit harder than that of the official mocks.

Official GMAT CATs.  These are the only mock tests I would recommend for the latter part of your studies, when you want to gauge how well you'd do on the real test. Other mocks may be similar, but I wouldn't trust their scoring algorithms completely.

GMAT Club forum question banks.  These were an absolute godsend for late-stage prep, when I just needed to drill myself with lots of hard questions. Surely you could buy the MGMAT question bank or something similar, but most of these are available on GMAT Club anyway.

Mock test results 
Economist CAT - 610 (Q38, V35)
MGMAT CAT 1 - 650 (Q39, V40)
Veritas CAT 1 - 660 (Q44, V37)
GMATPrep CAT 1 - N/A
GMATPrep CAT 2 - 770 (Q50, V45)
Veritas CAT 2 - 730 (Q50, V40)
Economist CAT - 770 (Q51, V45)
GMATPrep CAT 3 - 710 (Q48, V38)
GMATPrep CAT 4 - 770 (Q51, V42)
GMATPrep CAT 5 - 740 (Q49, V42)
GMATPrep CAT 6 - 760 (Q50, V42)
Actual GMAT - 760 (Q50, V41)

Tips 
 
 Spend some time on learning proper strategies for tackling "standardized questions". By this I mean questions like overlapping sets, combinatorics and work rate, where there is a simple way to tackle or write out the problem, and which doesn't really change for different questions. 
 Use the official guide to get access to lots of practice questions, but don't expect any strategy. Also ignore the quant explanations. They very rarely provide a method you'd want to actually use on the real test, and make things way more convoluted than they need to be. I'd recommend just looking up the question on GMAT Club afterwards, and reading one of the expert explanations. In short, the OG is recommended, but definitely not sufficient. 
 Use the GMAT Club forum question bank, but use the filter settings to get questions only from GMAC and Manhattan and Veritas and whatever else you trust. This is to avoid getting garbage questions that are nowhere close to the real ones. 
 If you haven't done any questions from a particular area (say RC) in a while, do a few of them before you attempt a mock test, to get back into the swing of things and to avoid getting completely stumped. 
 Avoid dragging out your prep over more than 3-4 months, so you don't get burned out. 
 Last but definitely not least - when doing a GMATPrep CAT, do not, and I repeat...  DO NOT ... close your browser tab. You will lose all your progress. I learned that the hard way.

Thank you for sharing your debrief, Toffelfabriken, and congratulations on a fine score. I will chalk up another victory to the MGMAT guides. The only question I have is related: Did you use the old set of guides or the newer, more concise version that was released earlier this year? I ask because all the great feedback I read seems to refer to the older set, and I am trying to see whether anyone has used the new books to such success.

Thank you again.

Any advice on quant? I have the same verbal score as you but am stuck on Q48 since a month. 
I dont plan on achieving a Q50 but a Q49 would boost me tremendously

Toffelfabriken · Answer

Hello Andrew

Thank you for your kind words.

Most of the MGMAT books I used were from 2012 and some were from 2016. I was not even aware they had made a more concise version. As such I cannot say much about what has been improved, unfortunately.

Toffelfabriken · Answer

Hello Kiran and thank you for your reply

The other sources I used for practice questions were The Economist, which I found to be similar enough to the real deal, and sometimes E-GMAT, which was good if I wanted some pretty hard quant questions.

freedom128 · Answer

What date is your last exam? Recently, I heard ppl recently complaining that gmatpreps are much easier than the real test.

How do you compare between the gmatpreps vs. mgmat cat/Veritas cat/economist cat? Looking forward to your sharing with us.

Congratulations!!! you did a great job. I'm at the very beginning of my GMAT preparation. I have a problem with the meaning understanding of intricate sentences. Can I have any objective suggestions (not like you have to work hard) in this regard? Can you share any articles or resources which can help in meaning understanding?

Kudos for any help in advance.

Really helpful stuff. Specially like how you suggest boxing the prep to 3-4 months. I am working on a similar timeline.

Congratulations on your superb score and thank you for the well structured debrief.

Any chance you are from a German speaking country or the Netherlands? (I am basing this assumption on the username

Thanks for your strategy. I hope to use it myself.

I can't seem to find where to apply the Gmatclub question bank filters you speak of. Can you assist?

Hello,

My last exam was in mid-December. I would say the final exam was very similar to my GMATPrep mocks.

Personally, I preferred taking official mock tests because I could be certain that the scoring algorithm is accurate. I didn't take enough full third party mocks to really determine how similar they are to the official ones, but I'd say the questions themselves for MGMAT, Veritas and Economist are definitely good enough to practice on. My advice would be that if you intend to take third party mock tests, then take them early on in your prep. This is not to get an accurate score estimate, but to identify your weak areas and to practice time management. During the last 1-2 months, I'd suggest switching over to official mock tests, because at that time it will be more important to get an idea of what your score will reasonably be on test day.

Toffelfabriken · Answer

Hello and thank you,

My advice would be to look at the sentence and try to shave off all the "unnecessary" elements of the sentence, like modifiers, until you're left with the left with just the essentials (subject, verb, object etc). I believe the MGMAT book on sentence correction has some of this stuff in the modifiers chapter.

Another general tip for sentence correction in particular is that if the portion you're meant to correct is only a very small portion of the text, then carefully reading the non-underlined portion is almost always very important for reaching the correct answer. They wouldn't include a very long non-underlined portion for no reason.
