The way i learn/study for physics is by writting up my own notes. This allows me to identify what i dont understand properly (i cant write anything for that certain topic). I can then research/ask someone/etc to pick up what i dont understand. Then to study, i just read my notes, and then try to write down everything i know about all the different topics. The topics i dont write down well enough, i re-read my notes, consult other books, etc. to try to get a better understanding. People say past papers are good, but i havent done any of those yet.
