Hey Mike,
I am Prashant.
I gave GMAT last September and got 660 with the split of 43 Q and 34 V. In my mocks I was getting 49-50 in Q consistently, so I didn't actually slog through quant and in last 2-3 days before the actual exam I rushed through the data sufficiency part. 43 in Q was a heart breaker, when a 49-50 could have breached the 700 barrier for me. I have decided to give GMAT again ( couldn't do so in past 3-4 months as I had to travel a lot for work) . I don't want to be inundated with a lot of material. For verbal I am using GMAT official guides, manhattan SC guide. What I am afraid of is the quant now. I am decent at quant, with good fundamentals in most of the areas(Engineering background) except few such as time and work, difficult questions for set theory, probability. What I think I am particularly weak in is number theory. I observed this during the exam that I was taking a lot of time to analyse the questions. e.g. I have chose 2 as my even number then testing it for all possible
cases. OG quant is easy except few 30-40 questions at the end. Also, Data sufficiency has at least 100-120 good questions, I am weak in DS as well.
I will work through OG but before that I want to get my basics right and hone my quant skill back to the level when I was in school and college. I have seen the
MGMAT's 5 guides, Jeff Sackmann's guide and Nova math bible and Nova DS book(Nova and Jeff Sackmann are suggested by my sister who scored 770 few years ago) .Can you please suggest, what should I focus on ?
Thanks,
Prashant
Dear
Prashant,
I'm happy to respond.
The OG and the
MGMAT books are good. The Nova books are good for practice problems, but of course, they don't have explanations. If you get Nova questions wrong, you really need to search here on GC, or post here, to get expert advice. I am not familiar with the Jeff Sackmann book.
The first thing I will caution you about is levels of understanding. It's simply not enough to say, "I understand." That's too naive. See this post:
https://magoosh.com/gmat/2012/understand ... rformance/Second, it seems your studying is very practice-question-based. I would recommend that you spend a lot more time with problem explanations. Look at the explanations even if you get the question right, just to make sure you did the question in the most efficient way and got it right for the right reasons. When you get a question wrong, it is entirely inadequate to look at the the explanation and say, "Oh, yeah. That's what I should have done." That does not build understanding. The question, for each problem you get wrong, is: what level of studying do you have to invest so you don't make that mistake again, so you are absolutely solid on that particular concept or skill the next time around? Also, it may be that shifting your perspective would help. See:
https://magoosh.com/gmat/2013/how-to-do- ... th-faster/ Also, I would highly recommend
Magoosh. In addition to over 800 practice questions, we have video lessons. Even if you know a fair bit of the math content, I believe learning time-saving strategies could give you the edge you seek. Furthermore, each question has it's own video explanation, for accelerated learning. Here's a free DS question:

https://gmat.magoosh.com/questions/1024Here's a free SC question:
https://gmat.magoosh.com/questions/3586When you submit your answer, the next page will have the video explanation.
Does all this make sense?
Mike
