I know I posted a thread about relationship between the knowledge of physics and the person's Physics gpa . I have a different question: What advice would you give to physics students on how to go from C and B to A and B students. I average in at least 1-2 hours a night when working out physics problems.

I would love to hear some advice on good study tips on how to get better grades and maybe hear some success stories of physics students who use to get C's and B's but are now getting A's and B's.
