Our class has only completed ~50% of the Physics B Curriculum!! We have done everything except the following: Fluid Mechanics and Thermal Physics, Waves and Optics, and Atomic and Nuclear Physics. We are currently working on Waves and Sound and will probably only be done with optics before the AP exam. That leaves around 40% of material that we haven't covered. How much should I start studying each day for the AP exam? I have Barrons 3rd Ed. and PR 2007 for AP Physics B and my College Physics (Serway,Faughn) text book. Should I use these books conjunctionally or should I just focus on one? What section that I've listed above should I study first?? I've taken a practice exam and I'm skipped tons of questions (around 20) relating to thermal physics and optics and some nuclear physics. Which sections that I listed in the first paragraph are the easiet to understand? Should I just study the according to the content outline that lists the percentage of expected problems that will appear on the exam? What should I do? Thanks. Should I worry about depth or breadth at this point? Should I simply go over the equations and basic concepts of each section with the cost of not understanding the concepts in depth or should I focus more on depth than breadth and really dig into the concepts? What should I study after waves?? Thermo and fluid?
