Hi,
OK, sounds good. It seems like you had a lot of test stress on the Quant section and never really gave yourself the chance/time to properly solve questions. Test timing and strategy is something that we can discuss closer to a second exam. Here are a few things that can help for your preparation:
1. Re-do the last 1/2 of OG 13 DS and PS keeping track (an
error log) of the ones that you get wrong or find difficult. Do these questions under semi-timed conditions:
keep your momentum moving forward, do not dwell, if you are stuck use process of elimination to pick an answer and move on (in general,
keep the time per question between 1 min and 3.5 minutes). You can do these in sets of about 10 or 20 depending on your time. After you have done the set, analyze the questions for as long as it takes to really understand where you went wrong and how to best solve them. Use the OG explanations, GMATClub, and any other resource to find alternate solutions and re-solve using those solutions.
Often, students look at the explanation and think "ah! got it" but it is not enough to look you have to put pen to paper and resolve yourself.2. Beyond OG I would
buy questions pack #1 and run through all the medium and hard quant. Same process as above. Do these after the OG because they will be new to you and it would be great to approach them once you have already gotten your process down.
3. After about 10 days of this I would start with timed Quant sections every day or so. I would
use GMATclub or MGMAT tests although my preference is to mix them up because they each have their strengths. Do not bother with the verbal. Do the same process of error logging and analysis after each sections. Don't worry about the scores, just learn as much as you can and get your timing/rhythm down
4. For verbal do all of the verbal review 2nd edition and all of the SC and CR from the 10 FLTs (available on this forum).
Keep an error log so that you can see which types of questions you are getting wrong so that you can focus studying in those areas. For verbal timed sections buy the GMAT Paper tests and use the Questions Pack 1. For the paper tests do all the sections in succession and add all the time together. It is OK to give yourself an extra 5 minutes so give yourself 80 minutes total for all three sections.
About 2 weeks before your test re-take GMAT Prep 2-3 times and make sure that you are feeling 100% with your
error log for both Quant and Verbal. The week before your test do the three GMAT Focus tests, two GMATPaper Tests (just verbal), and review your
error log.
A few notes on studying.
Analysis of wrong answers is just as important as solving questions. Make sure to leave at least as much time for analysis as you do for solving questions.
Studying when you are focused and rested is so much better than studying when you are tired and distracted. In fact, I would go as far as to say that studying when you are tired or distracted is counter-productive. Many of my students have found success studying BEFORE work rather than after.
Quality is so much more important than quantity so don't be afraid to take a day off when you need it. This will take a dedicated month but it is within the realm of possibility and at the end of the process you will have your score and will be a step closer to your goals. Let me know if you need more advice on this or have any questions.
Happy Studies,
HG.
PS: In general, I would stick with only official material for practice and
MGMAT and GMATClub for tests (only quant).
PPS: Reading a solid periodical like the economist every day can boost overall verbal score. You can search for posts on this.
