Yeah the textbook is a must. You don't really need the solutions manuals, but some of the CAPA questions were identical to the questions at the end of the chapter (some of which had solutions in the manual). Overall, I would say the manuals weren't that helpful, because you could solve the CAPAs through study groups, online (Yahoo Answers, Jiskha), or the TAs in Thode. I personally found the TAs to be extremely helpful!! I just wish I took advantage of Physics help from the start. When preparing for the tests, make sure you can do all the CAPA questions because sometimes they took test questions right out of the CAPAs. The lab manual was all online except for the pre-lab questions which you need to hand in:

Overall, this was a hard course. You really need to be prepared and have done the readings before you go to lectures. But anyways, hope you do AWESOME!
