I took Kin 1Y03. I absolutely loved it! It's really fascinating in terms of course material. The course load is pretty light--you have a 15min quiz each week, on the previous two lectures, and a prelab quiz before each lab (5 labs total, and about 20mins per quiz). The labs themselves are half lab, half tutorial, and all of your marks for the lab come from the prelab quiz + attendance, so it's pretty stress-free. Some of the labs are pretty cool, such as blood typing and hematocrit. The only real work from this course comes from the 60% final exam.
There's a lot of memorization in this course, but even for someone like me who fails at memorizing, it wasn't difficult to get a good mark. The course outline for it can be found here:

I can't remember the exact topics we covered in 1Y03 (it blends together with 1YY3 in my mind), but we definitely did embryology and the nervous system...the course outline should go through that in detail though.
