The Mosby's got me really acquainted with the material. I did all of the practice exams and when I finally sat for the PTCE it was amazingly, even eerily, similar.
Farah, don't be nervous AT ALL. It's really easy, and the passing score is pitifully low! Just be quick on your conversions, know what DEA form goes to what, general medication knowledge (A statin is used to treat: _____) and you're good to go. I'd never set foot in a pharmacy when I took the PTCE and nearly aced it out.
