So does that mean if you had to solve problems that were derive the equation sort you’d do well or badly? (Curious since I’ve mentioned this before but the questions we got on tests in my first physics course ended up being “derive the equation” sort of problems. Basically they’d tell you that you had an object of mass ‘m’ at distance ‘l’, or that there was an angle ‘theta’ and what not.) Personally I found that sort of question quite a bit harder. (It was very easy for me to screw it up since there were no number on the test except your score.)
