Which books to do first

That really depends on you. There is no magic pill for prep.

Have you taken a diagnostic test? That will tell you where you need to focus and how much time on the various subjects.

Plan to be done with GMAT in no more than 3-4 months, otherwise, you are waiting too long and will be past the peak of your performance.

Another key to success is working on the test when your mind is fresh and doing it methodically.

Gmat toppers on this forum suggest to start gmat prep with quant and then move to verbal as you can forget many rules in SC when you reach close to exam date .So its suggested to do math before verbal .

I found the information on this site valuable. Using recommendations of others and from book reviews from this site and Amazon etc I decided to do the following:

- Take GMAT prep
- Go through general strategy (Kaplan Premier) and all questions from that book.
- Take another CAT exam
- Go through all OG questions
- Address with specific books (eg. Quant, verbal, or SC, PS, DS etc).

The general book I used was Kaplan Premier online and it’s not really too hard to get through, although it very much depends on your time. You can go through each section in 2 nights if you wanted to, which is what I did. At that rate you’ll finish the entire book, questions, properly review your wrong answers, and create your error log in about 2 weeks. After all this I realised SC was my weak point so I’m going through MGMAT SC as well as OG at the same time. I personally wouldn’t recommend going to specific books before going through general strategy, as you don’t know where to focus your efforts.

The rate you go through books depends on your own pace and date of your exam. I’m intending to take my GMAT in 2.5 months so I wrote out a schedule and am sticking to it. This helps me to keep focus. There is a sample schedule on this forum as well. Good luck.
