Pharm help resources!?

Hello everyone:coollook:, I took my pharm class a while back in another city and the instructor was a new doctor and his first time teaching. The sad part is he only gave our test on the end of chapter questions. Which were only simple questions and a med as the answer. ex. This lady has gout which medication would she be given. Something to that affect. Anyhow, We did not learn how to calculate meds. When I started nursing school:D in the fall I was LOST :confused:also due to extenuating circumstances I had to drop:mad::mad::crying2::crying2: Completely beyond, anyhow it was horrible what I went thru, Depressed for weeks, still am). It was the hardest thing I ever did because I worked so hard to get there and got in my 1st time. Where can I get help (websites?) to do so. I will return next year sometime and want to be prepared I refuse to give up on what I know best and what I choose to do with my future. Also, its it true you can only attempt the nursing program twice in your life? I was told so. I am in Austin Tx. Thank You Guy's!!!!
