I would reccomend doing a lot of hard work for the midsem of this exam, all on exercise physiology, as the end of semester is only on biochem, which is very full on and overwhelming. The biochem lecturer calls himself a `giant dick`as he marks his exam so hard, `there are few correct answers, lots of wrong ones, and you wont get any pity marks from me`. This is an interesting subject, but make sure you stay ontop of the workload, you definitely wont be able to cram for this one.
