I took Physics IL03 last year with Dr. Nejat and I have to agree with last two posts. There were very few biology based questions (and if I am remembering correctly, out of the biology questions, one was on Lucy and one was on the ossicles).
I would not recommend memorizing every single diagram and the location of the various parts. You should know the biology concepts, but I doubt you will be tested on specific details (focus on the general idea).
The main part of the exam was made up of calculation and theory questions (a lot of theory questions!) Some calculation questions were basic while others were more complex. However, I would not say that any questions were more challenging than the questions from the tutorials/quizzes/CAPAs.
Hope that helps and good luck!!
