I have had a lot of pharm on my exams, I am a repeat test taker! It seems no matter what meds I study whether its prefixes, suffixes or contraindications it doesn't help! The types of questions I had was "which prescription would you question?" And it would list four different medication with four different types of patients! Very hard, so I would do some research as to which meds are commonly tested, that's the best advice I can give. Good luck!!!
