I used it during second year and found it really helpful. Memorizing abstract names is probably one of the hardest things I have to do. What I would do is print out all the kisspharm powerpoints that go along with each lecture. During study time, I would watch kisspharm and take active notes. Then I would study the actual text book (Brenner's for my school). It definitely helped. Unfortunately, my pharm professor was a left over from the paleolithic who would regale us with stories of what it was like practicing psychiatry before atypical antipsychotics were developed. (Yes he was that old. class of 74). My teacher did like to focus on a lot of tiny minutae some of which wasn't in the text book.
Anywho, I did find the course really helpful. Having the names and class MOA's down is really helping me out now for the step. My pharm score in uworld is consistently in the 70's.
