An important thing is repetion as well. On Day -1 (day before lecture) read through the syllabus and go through the powerpoint. On Day 0 (day of the lecture) go to class and absorb what is being taught. If you are already aware of the topic, it will enable you to stop taking notes on points that are already mentioned and take notes on things the professor has shown to you in a new light. Spend time with a book if necessary to clear things up further. On Day +1 (day after lecture) go through the syllabus again, writing up an outline or notes in the margin, or whatever works for you.
Make sure to look at the material in a different way each time. Definitely stay on top of the material. Never say, "I'll just do this on the weekend," because you will not. Tests come fast and furious in an SMP/medical school and you will not be able to carve out a huge chunk of time just to study for the exam. The only way to do it is to stay on top of the material. Also, don't be too quick out of the gate, an SMP requires stamina, it is a marathon. Pace yourself.
Good luck!
