Last semester I had Biochemistry and Molecular Biology, Human Physiology, Principles of Human Structure and my breadth was Business Finance. The three science subjects were all pretty full on, with 3 lectures a week each, there's a lot of content to be covered. If I had my time again, I'd definitely have done Research-Based Physiology last semester. But as long as you keep on top of things, it's not too bad a semester. I got H1's for BCMB, ANAT and FNCE, but my PHYS score was 74, which I was disappointed in. I heard too (from the lecturer, Charles, awesome lecturer) that they marked the physiology a lot harder.
The BCMB exam was actually pretty good, quite straight forward questions, different lecturer's have different formats in the exam. For example the kinetics section of the exam was like 4 MC questions worth 3-4 marks each from memory, while the proteins section was a 10 mark question, and then 10 marks allocated to one-word short answer questions.
Among my group of friends, we found anatomy the easiest (reflected in our scores too). The questions were quite straight forward (pretty much rote-learned stuff). And as peedles mentioned, you get a lot of choice in questions, so if you have a weakness (i.e. Virgina Grossman and her embryology lectures, the horror!), you can just choose another question.
My weakness when it came to physiology was definitely my mid-semester exams, mainly the second one where I scored 18/30. The exam itself wasn't bad, though I had a horrible miscalculation in time during the exam, and spent twice as long as the first question as I should've. The questions are the hardest ones in my opinion, cause it's situations where you have to apply knowledge to the question, instead of just spilling out rote-learned answers.
EDIT: Looking at your sig peedles, we're doing the exact same six science subjects
