Seriously. Enjoy first semester. Everything goes to hell with EM and optics. I also see you folks have to answer ALL the "free response" questions. That sucks, last year we always had at least one we could skip.
The best way I found to prepare for the exams is to look at the problems, draw out what is going on, and WRITE IT OUT IN DETAIL. Don't just say it to yourself in your head, write it out and force yourself to justify absolutely everything in writing. In my case, I found it makes all the difference in all my classes, because if you just go through it in your head, you'll allow yourself to make assumptions that you really don't know how to justify, which can leave gaps in your base understanding. Those gaps (in case you haven't noticed) are what 50% of the physics exams are based on. Writing it out also forces you to revisit stuff that you learned weeks ago, so it never falls into the abyss, which makes exam prep that much easier.
Once you're convinced you've explained it in detail, you're pretty much done. The explanations you've created will tell you which equations to use, and you just need to plug it into your calculator.
Another tip; particularly as the math becomes more convoluted: dimensional analysis works miracles. If you can't figure out what the hell is going on, work with the units you have to get the units you need algebraically. Also a good way to check your answer. If your units aren't right, neither is your answer. I'm sure you've heard this ad nauseum, but it saved my ass many a time on the exams, particularly second semester, when you have absolutely no frame of reference to what you're dealing with.
Doing this stuff is tedious, time consuming, and boring, but in the long run will drill the subjects into your skull and ultimately make life a lot easier (this all applies to the chems and bio as well). Just my 0.02.
