I think that you need to find out what your missing on bio. You might mainly be missing the orgo. If so, just focus on memorizing the reactions and obvious facts. If it's mostly bio, then see which subject you're weak in. I think mine is the physio/neuro stuff. I also need to memorize the hormones. What I like to do during the exam is I complete the bio passages first, then the orgo. I do the independent questions in order while doing the bio passages.
For the physical, get all the physical science sections from AAMC tests and do them all together in the same day. I mean do this after you've finished them. I'm kind of surprised that a lot people don't do many tests but review a lot. I thought that my review was worthless without doing all those exams. You need to hit the ps section of the exams over and over until the test. If you do that, then I'm pretty sure that your score will be a 10.
About the physical, my advice might be weird, but it worked for me. I can't really see how ppl expect to get at least a 10 w/o doing a lot of exams. Bio on the other hand relies a lot less on repetition and more on just luck of the draw. I occassionally do better then the previous test, but it's nothing that's completely consistent.
hope this helps. later.
