PT like there is no tomorrow. Get as many PTs as you can and do them under similar conditions as the real deal (but be strategic about it. You don't want to burn thru all of your PTs right now and then have 2 months of sitting on your hands before the test). The most important part is review afterwards though. It sounds like you may already be doing this, but perhaps your review isn't effective enough. The games section is the easiest to make improvements on and you should be getting 0-1 wrong on average for that. Most of the test seems to be about pattern recognition be it recognizing the game strategy during games to recognizing the arguments in LR. Just keep chugging through those PTs and make sure to put in as much time reviewing as you do actually completing the tests. As far as the RC is concerned, that is hit or miss among test takers I've seen. For some it is really easy for others it is difficult. I had difficulty with it because I come from an engineering background (which gave me a bit of an advantage with games). I think the best advice for RC is just to get your mind used to churning through thick passages/articles quickly and understanding them enough to where you don't need to constantly refer back to them. The advice I have seen from a lot of people is to start reading academic/thick publications like the economist to get your mind in the right arena of thinking.
Hope this helps
