Do not take Cell Biology, Biostatistics, Behavioral Science and Genetics lightly, people often think these are easy and then on the exam regret not studying for it more, you can lose simple points for not studying these well. Also practice all equations like in Pharm, Cardio, Renal and Biostatistics. The only thing worse than losing a point is losing an easy point, in this case where all you had to do was plug in the numbers.
When doing Qbank only do Timed Mode and Random Mode to really see where you're standing.
