DAH! im taking the exam in 2 days and I feel so unprepared... i keep hearing that it is easy, but there is so much information. I am using the mosby's review guide and im only done with chapter 1. For anyone that took the test... do i need to know all the conversions? Metric, household, apothecary, apothecary metric? I've never even heard of apothecary... Any advice on what i should be focusing on?
