Hi DonVito,
Integrated Reasoning actually has a lot in common with Verbal CR (and to a lesser extent, RC), so improving those skills in the Verbal section will likely help you to pick up points in IR as well. Since you're on a limited timeframe, we'll need to be efficient with the time that you have, so we should start by defining how you've been studying and your overall timeline going forward:
1) What study materials have you used so far?
2) 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)?
3) What are the exact application deadlines that you are facing?
4) Going forward, how many hours do you think you can consistently study each week?
You might also choose to purchase the Enhanced Score Report. While the ESR doesn’t provide a lot of information, there are usually a few data points that we can use to define what went wrong on Test Day (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you.
