Background
I’m an Engineer. Graduated in 2005 and worked with a Global Manufacturing giant for 1.5 years. Joined a startup in the Building Materials industry and have been working with their Operations team for the past 3 years.
Decided to give my GMAT in 2007.
GMAT attempt 1- Nov 2007: 680 (Q49, V34)
GMAT attempt 2- Oct 2009: 750 (Q49, V42)
Decided to retake the GMAT ‘cos neither was 680 reflective enough of my capabilities, nor was it good enough. I knew I had to work a lot on my verbal to improve my score. I restarted my preps around about feb or mar in 2009.
This is a list of material that I used most extensively:
Verbal:
1.Manhattan Sentence Correction Guide 4th edition
2.Official Guide 10, 11 & 12
3.Verbal Review for Official Guide 1st & 2nd Edition
4.Manhattan GMAT online forums
5.Kaplan 800
Quants:
1.Offical Guides
2.CAT material from IMS/Time
3.Quantitative Aptitude by Arun Sharma
4.GMAT Club Maths Tests
Test Resources:
1.GMAT prep (latest version)
2.GMAT prep (older version)
3.Powerprep
4.Manhattan GMAT tests (MGMATs)
5.GMAT Club tests
Sentence Correction
SC was my weakest section and one that scared me the most. Going into the GMAT it was my strongest..!!
Manhattan SC guide is a must have for anyone looking to do well in SC. Buy the latest edition if you do not have it already; you’ll get access to the 6 MGMATs as well. Do OG10 and OG12. You can skip OG11 if you like. Go thru’ the explanations given in the OGs; they are invaluable. And please
do the OGs at least twice.
Verbal Review for Official Guide 2nd edition is also highly recommended.
Stay away from 1000SC if you are just starting your preparations. They contain a lot of non-standard questions and some of the answers in the guide are wrong. You can use it later on in your prep, when you are more confident with SC. Also,
thousandsc.blogspot.com is a great resource for answers and explanations.
Start referring the
Manhattan GMAT online forums. The teaching staff is very active on these forums and always offer great solutions and explanations. Stay away from other online forums and their typical “SC question of the day” and “SC discussion” threads (including PG.. sorry..!!). The reason is that none of the posters in these threads are experts (except maybe a few) and often endorse the wrong answer and explanation with all the confidence in the world. You’ll only end up getting confused. Also, most of the questions posted in these threads are non-standard questions and not what you will see on the GMAT.
Practice, Practice and more Practice..!!
This is the only way to improve your SC performance. With enough practice you’ll be solving SC questions in less than a minute’s time. Most SC questions have the
3-2 split. You’ll start noticing it as you practice more and more. Eliminate bad choices immediately. Typically you will end with 2 close choices with even the toughest of SC questions.
Critical Reasoning
This was always one of my stronger sections. But yet, I found it to be the toughest on the GMAT. The difficulty level of CR questions on the GMAT was definitely higher than what I had come across during my preps.
OGs and the Verbal Review are the best resource yet again. Do as many questions as possible. With enough practice you’ll start seeing certain patterns. Strong language and assertions are normally never right when it comes to evaluating an argument or determining assumptions.
There aren’t a lot of rules that one can use for CR and there is not much you can do to improve your accuracy other than practicing as many questions as possible.
PowerScore CR bible: I never read it cos it was a huge document, but I hear great things about it. Do it if you have the time and feel it is necessary
Manhattan CR guide: It’s a short guide and pretty concise. Go thru’ it once or twice.
Reading Comprehension
Another problem area for many. I was scared of passages on feminism, labor reforms, civil rights etc earlier. But by the time I took my GMAT I was getting every RC question right on my GMATprep tests and wouldn’t be surprised if I got them all right even on my GMAT.
The key here is to understand the passage clearly instead of looking at the questions and searching for the answers in the passage. During your preparation,
take your time to understand the passage before attempting the question. It’s ok if it takes multiple reads before you understand what the passage is trying to say. With practice your speed and accuracy will definitely improve.
Again, there are no rules or tricks for RC. You have to figure out which strategy works best for you. What works for one may not work another.
Start reading
quality editorials and articles online. Suggested resources: New York Times, WSJ and editorials in The Hindu (these should you help you with your grammar and general diction as well).
Quants
Having taken my CAT multiple times, I was pretty comfortable with PS. But DS is the real kicker here. I screwed up my quants royally on the GMAT. Ended up with a mere 49 when I should’ve scored at least 50..!! Reason: lack of practice and speed.
Do not take Quants lightly. If you think you are good, then aim for 51..!!
DS is very very different from the questions you see on the CAT. And tough DS questions are what will decide your Quants score.
Except for a handful of good questions, OG’s are crap when it comes to Quants. I would suggest the
GMAT Club tests and MGMATs (Manhattan GMAT) for better and tougher questions.
Number systems is the most important topic in DS on the GMAT, so be thorough with your basics. Please go thru’ the Quants theory in the OG to understand the scope of what is tested. Do not waste your time on learning things that will never be tested on the GMAT.
GMAC offers
GMAT Focus for $25 on their website. This is supposed to be pretty good. Never tried it though. I did not go thru’ the 1000PS and 1000DS documents, so can’t comment on them.
Mock/Practice Tests
GMATprep: What you score on the GMATprep before your GMAT will be within 10-20 points of your actual GMAT score.
There are two versions of the GMATprep software: one is the latest version on mba.com and the other was released a couple of years back, in 2007 (just google “gmatprepsetup.exe” and look for a file with filesize different than the latest version. The smaller file is the older version). Download both for extra practice.
The GMATprep exams can be taken at least twice without seeing too many repeat questions. Please make sure you take at least 2 GMATprep exams right before your GMAT at the same time as GMAT appointment.
My GMATprep scores during my preparation:
1.GMAT prep 1 (2007) -770 (Q50, V47)
2.GMAT prep 2 (2007) -750
3.GMAT prep 1 (2009) – 750 (Q50, V41)
4.GMAT prep 2 (2009) – 750 (Q49, V42)
Before my GMAT:
5. (9 oct) GMAT prep 1 (2007) – 770 (Q50, V45)
6.(10 oct) GMAT prep 2 (2007)– 760 (Q50, V42)
7.(12 oct) GMAT prep 1 (2009) – 770 (Q50, V45)
8.(13 oct) GMAT prep 2 (2009)– 750 (Q50, V40)
9.(14 oct) GMAT prep 2(repeat) (2009) – 780 (Q51, V47)
MGMATs
They are great for Quants practice and good for verbal. They are CAT in nature and the scoring algorithm is pretty accurate.
My average score over 6 MGMATs: 730 (don't have the breakup)
KAPLAN tests
Please stay away from these. They are just bad practice material. They not CATs and have very poor questions.
PowerPrep
These tests are excellent during the initial stages of your preparation. The scoring algorithm is the same as that on the GMAT. But the questions you see on PowerPrep will be easier than those on GMATprep. Also, most of those questions are now in the OGs
I’m sorry for posting such a long post, but I do hope that at least some of ypu can benefit from my experience.
I hope I didn't miss anything. Feel free to post any questions that you might have.
Thanks for reading
