Received a PM asking me to respond.
Agree with the others above that your quant is already very good and most of your prep will be focused on verbal. Obviously, you do want to keep your skills up in quant (and maybe even improve a little!), but you already seem to know how to do pretty well on quant, so just keep doing what you were doing.
On verbal, the biggest thing that strikes me is that you list only OG12 and Verbal review 2nd Edition as your source material for your prep. The OG books are the best in terms of practice questions, but those books aren't very good at
teaching you how to get better. For that, you're going to need some type of test prep book. There are lots of companies out there with good materials; ask your friends, ask your fellow BTGMAT students, check out the books for yourself... but find some materials that will actually teach you how to get better at SC, RC, and CR.
(Note: if you're just looking to maintain your quant score, then you probably don't need anything more than you already have. If you do want to try to improve your already-very-good quant score, then you could probably also use some test prep materials that teach you how to get better at various aspects of quant. Try to identify your biggest weaknesses in the more commonly tested areas and then choose materials that specifically address those areas.)

Finally, you don't say what (if any) practice tests you did. GMATPrep is the closest to the real test but doesn't offer you any data on your performance (beyond a score). So use a combination of GMATPrep and tests from a test prep company. (But don't focus on trying to take a ton of tests - that's not actually how you improve. CAT exams are really good for (a) figuring out where you're scoring right now, (b) practicing stamina, and (c) analyzing your strengths and weaknesses. The actual act of just taking the exam is NOT so useful for improving. It's what you do with the test results / between tests that helps you to improve.)
