I took the Kaplan simulated exam yesterday and to my surprise Physio was one my weakest subjects. did well in class ano on phys shelf exam, so i was really shocked. My question is i found i was really weak in renal and reproductive phys. Should i go through the BRS or use Big Costanzo to go through. I have 5 days set aside for physio review in my schedule i made up. Any suggestions as most of the exam was pathophys (which i did well in) and straight phys i think they said like 40 phys questions and 80 pathphys questions was on the score sheet.
