Hey there, I don't go to TMCC...I'm going to UNR, but I've had the chance to talk to some TMCC students who are currently in their nursing program.
Yes, there are med exams at TMCC, but like Suzanne said, I was told they have 3 chances to pass it. One student I talked to mentioned that she has only ever seen 2 students be held back a semester because they used inappropriate unit abbreviations and didn't necessarily get the math wrong. For example, answering 10U instead of 10 units.
At UNR we don't have med exams per se. We do have one prereq course that is 8 weeks of med calculations and 8 weeks of medical terminology
. If you don't pass, you don't get into the program. Since I've been in the program, I've had two med calc quizzes in clinical and they've been fine.
If TMCC doesn't require it, there are drug calculation books available if you'd like to practice. The one I used is called Math for Clinical Practice (ISBN: 0-323-02582-X) and I thought it was helpful. It teaches you how to do the calculations and gives lots of sample questions in the book and more on a CD-ROM.
Good luck getting into the nursing program!
