Hello Everyone ,

So after not figuring out my own i decided to share my problem on this forum so i can get help from the experts to help me out and letting me know wheres the problem or where i am lacking.

After doing MGMAT Quant books i started doing

OG 12 (could solve most of the question in time and my accuracy is good)and while solving the OG i felt confident so, to check my progress I took GMATPrep and MGMAT Test and in these two tests i find difficulty in solving the Quantitative problem ( taking to much time , not getting the final answer). So i got depressed and then again i started doing

OG 12 with no additional study again I can solve

OG 12 question with ease and with very high accuracy in time.

So anyone can tell why i am not able to perform well on GMAT Prep and MGMAT test while i can perfrom well on

OG 12 ( in timed environment) . Are the questions in

OG 12 are very easy in comparison to GMAT prep and MGMAT Test ? Any suggestions to improve my performance on GMAT Prep /MGMAT Tests just as on

OG 12PS : Are there any books only for questions (no theory like 5lb Manhattan GRE book)

Thanks,

Mohit

questions are of 500 - 650 level. Practice tests are adaptive, so if you do well on level 600 questions, you get tougher questions. Few questions of OG are 700 level.

Though, I think that if you are facing problems in GMAT Prep questions, it means there are some gaps in concepts. When I say concepts, I don't mean just Even + Even = Even etc. Those are 500-600 level concepts. It means that given a number, you will be able to deduce that it can be written in the form a^2 - b^2 if either the number is odd or the number has 4 as a factor. (Discussed here:

The point is, your basic fundamentals might be in place but are the advanced concepts clear? For more, check out my blog:
