Hi Danielle!
I'm actually an Anthro major...so I can totally help you out. I took all three of the classes.
Anthro 1A03 is cultural; in my opinion it was the easiest of the three, but the most interesting. you get to learn about different cultures, and how they function (ie north american versus a small tribe-based culture in new guinea). If the course format hasn't changed, you have marks based on participation and attendance of tutorial, a midterm, an essay, and a final exam. However I'm going into fourth year now, so it is possible it could have changed a bit. Some of my friends took it last year as an elective, and also really enjoyed it.
Anthro 1B03 is archeology. Now, I had a TERRIBLE prof for this course, but she was not re-hired. The textbook I had was very similar (and focused on more or less the same) units/civilizations that I learned about in grade 11 classic civ. There was a little bit more detail. My cousin's cousin took the class several years before I did, and the prof she had still teaches the class, and apparently is supposed to be very good.
Anthro 1Z03 is physical anthro. If you took the into to pysch/sociology/anthro in grade 11 you got a bit of an overview for some of the material. You learn about the early hominids in some detail; the time periods they lived in, what they looked like etc. We had tutorial marks based on participation and attendance, a midterm, two small (4 page) essays, and a final. Because of the content there is a fair amount of memorization involved, so it can be tricky. And, if PADIAK is the prof, EITHER SWITCH TO ANOTHER SECTION OR BE PREPARED FOR A DIFFICULT SEMESTER.
As for Paul's comment regarding Psych; I disagree. I started as a psych major and dropped out because of the way the course was taught. You are taught exclusively by a TA, and you will not see Dr. Day. Your lectures are videos of him teaching the course material from at least a decade ago. You do two group essays, have a midterm, and a final. And Dr. Dick's question format is not straightforward.
