I excelled in Quantum mechanics, but suffered greatly in classical physics...good with the small stuff, useless with the big stuff.

Why? Classical physics bored me to tears(I did like astrophysics). Something is infinitely more fascinating about the trajectory of atoms than the trajectory of a car......if you get my broad meaning.

Sorry I am not very helpful but one thing that helped is to learn your formulas off by heart and learn the language of physics like you are learning a language you are not particularly fond of. Work harder at it than anything else. It does start to click in to place eventually. Keep going.......don't give up because it does get interesting. Are you doing premed physics to do with fluid dynamics or something? Get those drips going?

Remember to laugh. It was the only way I retained my sanity.......

Take good care...
