The problem I have encountered is that physics is so difficult to understand. For example, during my last semester, I studied classical mechanics. There were two lectures plus one assignment consisting around 4 questions per week. At first I tried to understand how equations were derived and the examples talked during lectures. However, it was no longer possible to understand how equations were derived at later time because things were getting difficult. I could only memorized equations, like the non-inertial frame motion equation and lagrangian equations, without understanding how they were derived. It was bad, but it saved my grades. It is because if I kept devoting time into understanding how equations work without drilling exercises, my grade will drop as no drillings are done for exams. The exams from my lecturer are quite similar to the homework questions and so to survive exams drillings are important.

In otherwords, how can I achieve good grades and at the same time, understand how the equations work and the proofs? Or is understanding proofs and how they work unnecessary at UG level? And is it a normal problem for everyone?

My next semester is going to be electrodynamics. Is there any suggestion to study it well?
