Took it in Winter 2011 with Dr. Zhorov. The professor seemed like a nice person, but has tendency to read off the slides. Just go and listen to him, instead of taking notes. You will be surprised how much you can retain later.
Only take this course if you do not mind a huge amount of memorization. If that is your thing, this course may be for you, but if you think understanding is more important then think again. Almost everything asked was from the lecture slides, but you could be asked random things like [ATP], [glucose], enthalpy of certain reactions, etc. The part upto the 1st test is manageable, but after that, you have to memorize the Krebs Cycle, Glycolysis, Electron transport chain enzymes and substrates, etc. Attending lectures is not mandatory. Course content can be quite boring at times.
The key to do well in this course is to read the slides more than once, letting it sink in your brain. Study for recall and recognition, not understanding. Look at his previous tests to get an idea of what type and style of questions he asks. He also tends to focus on some things more than others (like asking about succinyl CoA ), but it may seem completely random about which things get asked and which are not mentioned in tests at all. There is always a bit of luck factor, you may remember a lot of facts but it won't help if you miss a detail he chooses to test.
Your entire mark depends on around 90 MC questions, so getting a 12 is VERY difficult because it leaves very narrow range of error. However, this course is required for a lot of future courses and professional schools.
Overall, this is the type of course for which it is easy to pass/ do mediocre, but difficult to do excellent. Double digit grades are possible though, but require a lot of rote memory!
Good luck
