Tks for the question: What is the best way to prepare for the GMAT AWA and IR in a short time? I would suggest that you do the same as it provides you a perspective as to what you are dealing with exactly.2.
Understanding the GMAT exam format and pattern When I started my prep the first thing I did was understand the basic structure of the GMAT; the sections, the duration, the number of questions, the scoring mechanism, and so on.
For Quant I did some questions that I found on the Internet.
I also practiced IR at this time, solving the questions given in the OGs and the GMATPrep software.
I started my preparation by thoroughly going through the Manhattan Guides.
At this point I would like to say that though the Manhattan Guides are good and provide you with a lot of relevant information (especially in the case of CR & RC); they should only be done if you have the time and are willing to put in the effort required to go through them and understand them.5.
After my semester exams got over (the date was 19th May) I resumed my GMAT Preparation.
By the way, my performance in my semester exams had been sub-par so I was a bit disappointed with myself.10.
I found a couple of notes (in PDF format) on GMAT Club and downloaded them.
These notes helped me understand the nitty-gritty of grammar and clarified the doubts that I had.
