I took the pre health and science program at seneca 2 years ago. I enjoyed it, though it is A LOT of work!!! I didn't take chem, bio or math in high school past the required grade 9 or 10 (can't remember). Talking to student who did take those courses in high school the pre health program is harder then high school, it goes into more details. The professors are amazing in that program (unless Peter still teaches math, then get ready to teach yourself). Overall you will need to study a lot!!! There are amazing tutors on campus if you require further explanation, i had the tutor teach me everything in math!! I ended up graduating with honors and getting accepted into both RPN and BScN programs at Seneca.
