| I don't know about Physics B, but I know that for Physics C, Barron's is by far the best that I've seen. Having taken Physics C Mech and E and M sophomore year while I simultaneously took Calculus, I'd bet my whole grade on this book. I don't understand why you would say dont waste your time on Barron's. Honestly, I think that if you're good at self studying, take Barron's. Their questions are a little harder than the AP Exam I agree, but I guess I didn't study up just to take the AP Exam. If you were to study both books fully, I would say that Barron's would leave you with better conceptual understanding (vital in Physics). PR tends to have a step by step process on solving problems which I don't like because it doesn't seem like physics anymore... it seems like... err well... the Macarena... 1...2... blah blah... HEYYY MACARENA. AIIII ^_^
Just my 2 cents. I'm not saying PR is bad, I just prefer to have it more difficult so that the AP Exam is easy. But for your case for 3 weeks, I'd go with PR (just because they have nice concise reviews that can be understood in such time.. its almost always like that.)... Have fun with Physics B man |
