My question is whether a student can apply for medical school in Canada after he/she has completed grade 12. I want to know if it is possible to just study for the MCAT after grade 12 and is the score is high then apply for medical school. Or do you have to go to university before apply?

Hi,

This may help: Applying to the Faculty of Medicine | Admissions, Equity & Diversity - McGill University (http://www.mcgill.ca/medadmissions/applying)

You must go to college first
