I had seriously started studying around mid July for GMAT, My first diagnostic test from some website in end of May gave me 590, so I knew I needed some studies
I used Princeton review,
OG 10 (free from somebody) and
OG 11 plus little bit of Kaplan.
Initially I thought I don't need to focus on MAths that much but later found out since I had not touched the kind of problems GMAT tests in like 14 years, I better brush up everything and practice a lot.
Verbal had always been weak for me (even in GRE), but kept focus and kept practising. I had never been a reader, I only read the stuff I needed to (technical). Took GMAT prep test and Princeton review tests, my score varied from 670 to 740 so I fell in the average of my test scores.
My advice: practice essays also when takign tests, while takign practice tests, i used to take long breaks between Q and V and this kind of hurt, Last time I took such a long exam was in grad school in 1999. So it does take getting used to
I already described my bad experience first time of taking test, when I didn't have the passport. Today i had it and took the test
Essays were easy, but I am a slow typer and if I try to tyoe fast, I make typos. So typed slowly and finished both on time and was able to revise them.
Quant: There was a mixture question, that I read wrong and was so frustrated not to find answers in choices that I was getting and later found my mistake. There was a ds question about two planes intersecting the sphere so please be careful, GMAT is testing new concepts too, lot of ds questions involving modulus and inequality, 1 Prob question, 1 combinations, one median, avg ds was so bad that I had to guess, In the end I was runnign out of time and finished with 15 seconds left, I was running out of writing space in the dying minutes so I had to ask fo rnew pad and that consumed 45 seconds
One question related to relative speed ds (Car A in front of B etc.) I knew I screwed up by hitting wrong button and I think I did that in hurry on another question otherwise I woudl have got 51 in Q
I was not happy about it but tried to forget about it and focus on Verbal.
Started with 2 SC, but next came a horrible Cr, spent 3 mins and made a best guess, then came horrible RC, where every sentence had some circualr reasoning. The later RC became easy but CR were much tougher than I did in GMAT Prep tests, I don't knwo what other recent test takers think, I think I started hurrying up in questions (I usually do that) and int he end had more than 2 mins per question and slowed down (bad strategy, sicne if you screw up initially, questions could become easier and extra time does not help)
I still wanted tto see my scores just to check how lucky I was in my guesses, I guess not too much, guessing does not help too much.
still I think My quaifications, GPA and wok ex would help me in apps, plus I have some leadership and volunteering experience. Hope I make to one of the 5 schools. I think I will apply to Cornell, CMU too.
