1) Biochem A was the main chemistry related topics, wasn't too hard and essentially just a bit more detail than at A-level.
2) Biochem B was genetics and although I found it boring, it is straightforward.
3) Practice if Biomed is statistics, but really only covers about 10 or so lectures.
4) From Cells to Systems is the structure of tissues at the microscopic level and was interesting although the practicals were a real drag.
5) Pharmacology was great. Not too hard, interesting and engaging.
6) Physiological Systems was quite good, basically learning about the systems of the body. CNS, Muscle, carciovascular etc. This exam was quite hard though.
For the first year I used the following books:
1) no book needed, the lecture notes were good enough (attendance quite key for these) Recommended textbooks don't add much
2) Essentials of genetics by Klug. Very good book and if you miss lectures, this book will make up for it
3) This is only statistics and some other miscellaneous topics. Only lecture notes, as there aren't any specific books. (attendance key)
4) Wheater's functional histology. very good and has most of the pictures used in the lectures
5) no book needed. lecture notes enough.
6) Vander's human physiology. Good book, maybe too detailed in some aspects for the first year, but it still comes in handy in the second year.
