I can relate mnw9412, in almost all of my pre-req's totally a A-B student. I've just taken my 1st Pharm exam after studying my butt off and failed. The grading scale has changed to where a C is now an F - I CRIED! After review the test and my answers, I realized I was over thinking it AND rushing. Break down the stem (what's being asked) and then eliminate the wrong answers, then based on what's being asked - decide and don't change it! Good luck!
