1. Calculations (Ansel especially is helpful)
2. After the metric test, focus on the areas of coverage in pharmacology/therapeutics that tested poorly.
3. Yes, there is calculus on the exam. No, you do not calculate any Michaelis-Menten non-linear kinetics, but you have to understand the reaction orders. You will have to calculate zero and first-order and they are covered in your calculations.
4. Calculations (notice a pattern here?)
5. You are testing very late in the season, honestly, with two failures, you need to look at your diagnostics. Reschedule the exam if you are not prepared, because you will have to redo a year should you fail this time.
6. If you do not intern, you should be. That helps immensely with getting the practical material down.
