vmrose, I have not spent enough time studying for dosage calculation tomorrow so I'm grateful I'll have one more shot in February! I'm strong in math so I think that helps but there's so much more here than that! Can you tell me is it primarily knowing your conversion factors and being able to do the math -- I don't have these million abbreviations memorized yet (ac, DS, ss, HS, etc.) but know the ones that affect the dosage (qid, tid, qd, etc.). Can you give me any more insight on what I should focus on today to feel more prepared for tomorrow? Thanks!
