Hi,
A 3 month timeline to prepare for the GMAT is good enough. Use your GMAT mock test scores as a direction to start your prep with.
As you have mentioned, Verbal needs attention at the moment. Get down to learning the basics first in Sentence Correction, Reading Comprehension and Critical Reasoning. I would suggest that you keep a good 2-weeks (on the higher spectrum) for each of these topics. Once you are a little confident with the concepts, get on to solving problems for the
OG 15 or
OG 16. Use ONLY official questions while you practice - no other material comes close to them (Refrain yourself from downloading free question bank PDFs online
)
Also, a key point to your study plan must be your
Error log. Write down a detailed explanation when you get a question wrong - revisit the concept and solve the question again. This will help you identify concepts quickly on the GMAT. You must know that on the real test you will have just 2 minutes for each question. So familiarize your brain to think under time constraints while practicing.
A word of caution here - Your Quant seems good now, but don't completely neglect it during your preparation. Push yourself to score a Q49 - Q51 consistently on the Mock tests that you would take. Even a one point increase in Quant can push your total GMAT score up by 4-points! So don't neglect Quant from your study schedule.
