The quant in the real exam is much much tougher than
OG problems. What mistake i made was that i had kept gmat prep for the last couple of days before the exam and when i started working on that, i found that the standards are totally different..but didn't want to cancel the date so took the test. faired well in maths though...50 was a good score. but yes...the standrads are not
og or gmat prep or princeton. standrads are
manhattan gmat, gmat prep ...for sure. my paper started with a super hard inequality which took me 5 mins to solve on the real test.
for quant i would suggest the following things:
1. gmat club : all 25 challenges...they are just toooooooooooooooo good!
2.
manhattan gmat : take the 3 full tests. the math section is very very good.
3. 800 score com -> maths is quite hard
4. gmat prep...maths is just what u get on the test
-----------------------------------------------------------------------------
for verbal, since i got 33 i am not a position to tell u anything. but u know. i didn't leave any gaps in prep. and the paper seemed so smooth in the real test. the verabl standard is same as
og. infact during the test, i was surprised that maths was seeming so tough and verbal is seeming so easy...but at the ned of the test, the scores crushed me down. 690 is a competitive score but is not balanced at all for me. its totally biased towads quant. for the verbal, i feel that i got the first 3/4 questions all wrong. then the paper became smooth and i couldn't get a better edge.
-------------------------------------------------------------------------------
regarding the first 15/20 myth, i would say that with the current gmat, u will get penalized less even if ur number of mistakes are more. it counts on the difficulty level. u can get 3 out of first 10 wrong and even then u can get 40+ in verbal ( i have got it in gmat prep). but first few questions, mistakes in a chain will finish u brutally.....also, i have seen for both maths and english, very tough questions are apperaing at the end too....
and even getting an easy one wrong at the beginning, if i could crack these, i could get 51. so each question is important and u can get kind of 50/40 combo with 5 mistakes in maths and 8-10 mistakes in verbal. but, first few questions, mistakes in a chain....a death nail! Thats what happened with me when i took the test, for the verbal section....one thing is for sure, if the paper seems very smooth then u r on the wrong track...
