Hi lepe9696,
When was the last time you took a FULL-LENGTH CAT (with the Essay and IR sections)? If you have not done that yet, then I suggest that you take one soon (perhaps this weekend). We need to know how you handle the FULL Test when taken in a realistic fashion (so make sure to take it away from your home, at the same time as when you plan to take the Official GMAT, etc.). Based on what you've described, I don't think that we have a realistic sense of your skills yet - and that information is essential to planning out your studies going forward. Once you have that score, you should report back and we can discuss how best to proceed.
GMAT assassins aren't born, they're made,
