As an added feature, one of our prior grads (who is also a current course editor) has shared this site for free with our students from his paid site. It can be used to check yourself with drug calculations practice. Remember, you are not allowed to use a calculator when doing the Pharmacology Qualifying Exam – just paper. So you can practice using the quiz practice questions inside your coursework (there are 100 there and the quiz will repopulate each time you use it) and you can also get questions from books or other websites and then use this link to cross check your answers if you like.
