I know that its different for everyone, but I've heard comments on these boards generally saying that the EK Chemistry boook was poorly written (i've heard a few saying the physics was kinda crappy too). I should be finished with EK Chemistry by tomorrow (i'm 3 days behind planned schedule). Will EK Physics go by faster? My biggest problem with the EK Chemistry was how vague it was and consequently had me a lot of the time deducing concepts and rationalizing things out to myself which sucked up a lot more time. I don't have trouble with *using* equations because for the most part it is plug and chug. Hence, I don't think it would make any difference to be using Princeton Review's Physics Book (becasue they focus on the simplest questions).
