Thanks for responding (I'll start using 1st person). I actually will be working on my M.S. after graduating next week and will be finished with the M.S. next year (a few of my classes in undergrad count toward the M.S.). My goal is to apply next year to med school.
I think your right about taking university classes and getting straight As in a few sciences, but there is just no time as I will be doing a M.S. This brings me to another question: Can courses in an M.S. count as the science LOR, or is it strictly from the science prereqs at the university? A few of the courses that I will be in for my M.S. are the same as the MS1 students. This is the description of the course provided:
"Core Principles System I: Introduction to basic medical concepts and biological system functions; examination of core principles of science and medical treatment."
It also includes a lab. So, will getting a LOR from the professor teaching this course count as a science LOR?
