طب عين شمس

Hello everyone! I've just been accepted into the Faculty of Medicine at Ain Shams university and I have a couple of questions regarding studying for the medical students in the later years. I already know about how the system is and how the grades are distributed. What are the most effective and time efficient ways to study and what are the best resources to study from? I'd really appreciate some advice pertaining this because I don't want to start the year lost and confused and end up wasting time.
