I kinda agree with freebird, and at the same time I don't. Yes most people have a tough time with biostats because the lectures are hard to understand and the TAs don't know what they're doing in the labs, thus you will have to learn everything from the textbook. However, the average for this course is similar to all other 2nd year biomed courses (~70-73%), and that's not gonna change. For the labs, you're either gonna get a nice TA who's knows what they're doing and is willing to help you or you'll have to rely on the people around you. Either way, the average for labs is like 7/10, and most people do get over 8 so not that bad (the lab experience just sucks - think of first year physics). As for lectures, just do the textbook questions and you should be fine for the exams, there's no other way around it (I like to do them during his lectures because if I can't understand his lectures and am forced to answer clicker questions for marks, might as well do something productive). He does give some practice questions before the midterms, and they give you a good idea of what to expect on exams. In the end, I would not do full year psych stats instead of a half year biostats - stats sucks period and I'd rather not learn about it for another semester. It's just not needed; biostats is frustrating, but not impossible. (just in case you wanna know, i ended with an 90% but I'm a low 80 kinda person in all my other biomed courses so i'm not pre-med smart at all, yet I did well in biostats)
