A repository of files for download. "General downloads" contains miscellaneous files of interest, inlcuding homework problems not found in the book, study aids, etc. In "Old exams" you'll find, well, old exams! "Other stuff" is other stuff, inlcuding online ideal gas property calculators.
Old exams for your studying pleasure. (Before you ask, no we don't have solutions available for download. That's on purpose! It's real easy to look at a solution and go, "That makes sense," and then incorrectly infer that you could have done it yourself without looking at it. The best study strategy is to work these exams in a timed manner and then assess your work afterwards.)
(Note that due to the changes in the order of topic coverage, there may be some topics on these exams that we have not covered yet, and some that you have already be tested on. Use these accordingly.)
