I'm going to start a degree course in physics next year. So far in high school I covered some physics without calculus. 
I know that I will start everything from the beginning at university, but I would like to prepare in some ways. Then the question is: what should I do? Should I revise what I studied? Should I go head? 

Can you suggest (from your experience) what should I do before starting a physics degree course?

PS In case you recommend to study some material, can you suggest a book?
