This is a general question, so I hope you don't mind the lack of specificity. How do you guys approach or think through any given problem? It's my first semester in undergrad physics and I find that, while I'm capable of doing the math, I'm bogged down or get side tracked in the process of A to B to C to the answer. This becomes particularly frustrating on examinations when I have a time limit. Do you visualize the answer and work backwards with general equations or vice versa or what? Any input would be great, thanks!
