Good. Some suggestions.
For RC and CR, also study why wrong answers are wrong. This allows you to use process of elimination to narrow down your answers, and it also gives you something to do when you've narrowed down to 2 and can't decide. If you know how the test tends to make very tempting but wrong answers, that can help you guess between the final 2.
For SC, do only some topic-by-topic (that is, so that you know what that question is supposed to be testing before you start doing it). Save some to do in random sets. The test doesn't tell you "parallelism question coming up next" - you have to figure that out. So you need to practice figuring that out.
Another thing that can help. Get a notebook (or make a computer file) and, on one side, list a rule (eg, parallelism). On the other, list clues in sentences that could tell you parallelism might be an issue. For example, lists of things, a comma followed by the word and, "XY" type idioms (both X and Y, not only X but also Y, etc.), comparisons (and then do another list for: what are common markers for comparisons? eg: like, as, unlike, as ___ as, ___ than, etc.)
Basically, consciously study how you recognize that a particular issue might be going on in a particular sentence so that you have an idea of what to do when you're reading a new problem.
Also, just be careful about your practice tests. Different people have different theories about this. Mine is that practice tests should be taken about 3 weeks apart until you get close to the test, and then you should take one 2 weeks before and another one 1 week before. That's it. Again, just taking practice tests without reviewing them and basing your study on them doesn't do a whole lot for you. And reviewing and changing your plan takes time.
At the very least, don't take a practice test within 3 days of the real thing. There's really no upside (you're not going to take that data and figure out how to incorporate new stuff with just a couple of days to go) and there are serious potential downsides - you could tire yourself out mentally, you could score poorly and psych yourself out right before the real test, etc.
Good luck - let us know how it goes!
