Stop taking the Kaplan tests. They are not realistic, especially for verbal. It doesn't sound like the class is helping, and it might not be worth it to continue. I don't know if their moneyback guarantee is good if you quit the class or only if you take the real GMAT and bomb it, but if you're studying Kaplan materials 2 hours a day and not getting anywhere, you need to do something different.
Use the Princeton Review books instead...Cracking the GMAT is MUCH better on strategy, especially verbal, and the tests are much more like the real GMAT. Do the PR tests and the official GMAT Prep tests. Don't waste any more time on Kaplan tests, because they will not reflect your real capabilities. Keep working with the OG, but use PR's strategies instead. I guarantee you will see an improvement.
