My school uses pharm made easy 2.0 so it may be different for you if you're using "pharm made easy"...BUT you should see 3 tabs, to the right, just slightly above your tutorial list (not the very, very top of the page)
The tabs say tutorials (which is where you find your "pharm made easy" tutorial), another that says "proctored assessments" (this is where you go to take your actual test and it is password protected like the above poster mentioned) and the last tab says "practice assessments"
This is the one you want to use to take any practice tests. We had 2 practice tests that said "RN Pharmacology practice tests," one A and one B test. I also practiced retaking each separate tutorial test again just for more practice. Good luck!!
