not to troll, but i find TBR to be pretty easy. but then again, i took physics in high school, and then again at my university. from what i've been seeing in TBR though is that its highly conceptual and less mathematical even though they really hammer the math home in the actual content review. the math doesn't matter though if the concepts don't make sense, you have to choose the right formula. also, i think you should also use intuition in the physics section. EK stresses this a lot, and there were some questions where you can almost intuitively guess. this works really well for TBR physics 1 since its mostly kinematics and stuff, it might not work so well with TBR physics 2 since its EnM stuff (who deals with capacitors, resistors, etc all day in real life?)
