Hello, few days ago I took an exam in my honors physics class and believe I did not do as well as I did on the other exam. Last exam had a few computational problems and the rest were general solution problems. This recent exam had 8 questions that were all general solution problems as opposed to the last exam which only had 4 or so. My question is how can I become better at finding general solutions. My next exam is on the laws of gravitation, shell theorem, and Kepler which are much harder topics than previous ones. Any advice or links geared toward general solution problems in these topics?
