yea i had a terrible time with it.
Two things helped me...reading over drjohns review, esp the "misc" section and diagnosis, and looking through savarese , which i will do again before the exam anyway (yes me, omm boy, w/e 😛 )
Dr john does a good job of explaining how "else" things are called... and read the explanations in kaplan, i found a lot of my mistakes were because of unfamiliar terms, so when they explain a question with a term you werent familiar with, write it down
