Hi toy9575,
Based on your question, it sounds as though you are putting more of an emphasis on a timeframe (1 month) than an outcome (a particular Score Goal) - and that can potentially be a problematic way of thinking (especially if you need to score at a particular level to get into your first-choice School and/or receive a Scholarship).
The speed with which you might make the improvements that you're interested in will depend a great deal on the work you've done so far. Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what dates did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
