Other people telling you their study habits won't really help you that much. I was doing the same thing that you are, but once I started school I realized that out of the 220 people in my class, there were probably 195 different study methods. Here are some generally agreed upon things you can do to succeed in medical school:
1. Don't fall behind. Medical school has so much material coming at you so quickly that it is easy to fall behind. Try your hardest to stay on top of the material. Review all of the day's lectures that day. Don't let multiple days pass before you review a lecture.
2. Repetition, repetition, repetition. This is definitely the name of the game. The more you see it, the better you'll do.
3. Don't go to class. This one may be not actually be widely agreed upon, but my grades definitely increased once I stopped going. I also found that I had more free time (read: time to study from materials that I otherwise couldn't find the time to study from before). I felt less stressed overall. I also was able to get a least another full pass through material before an exam.
These three should get you started. This probably seems pretty vague and not helpful at this point, but if you at least don't fall behind and try to make multiple passes through material, you'll do well. As far as making note cards, rewriting notes, putting all powerpoints into a word file, reading syllabi and then only studying board review books, reading Robbins (or other texts for that matter), these will all come down to personal preference and what you feel is the best use of your time. Medical school really is so intense that you simply have to find what works for you and not rely on what worked for someone else.
