Hi Faith09,
Each of the 6 Official GMAC practice CATs/mocks includes an IR section and if you purchase a new version of the Official Guide, then you can access additional IR practice online.
Before I can offer you any additional advice, it would help if you could provide a bit more information on how you've been studying and your goals:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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)?
4) What is your overall goal score?
GMAT assassins aren't born, they're made,
