Your request is a little vague but I'll try to help.
-First, get the idea of grades out of your mind, a patient doesn't care if you got a 98 on one of your orthopedic tests but whether you can help him/her i.e. learn the material to know it not to master a test.
-Try to put your hands on as many people as you can (classmates, friends, family, homeless people) because this will help you understand normal variation in the population that can still be asymptomatic.
-Depending on the timing of your rotations, I'd suggest doing a little observation time in the clinic just to get an idea of how the techniques you're learning are implemented in a real life situation.
-Don't change your entire world just because you've started school. If you wanted to study 24/7 you could but that doesn't make for a healthy balance. Get out and have some fun (the bars after finals are always good).
edit: some may disagree with this last one but whatever. For me I knew orthopedics is the only field I'd practice in so I spent most of my time studying for this and tried to relate the pediatric/geriatric/neuro classes to how it would help my orthopedic patients. PT schools teach you as a generalist so a little more focus on the field of your choice will help improve your knowledge base.
