anyone here have experience with switching from another program into engineering? specifically life science? are there certain courses you have to take to get in? what kind of average do u need? is it a difficult process to transfer to a different school? thanks

For switching from life sci to engineering within McMaster, it is definitely possible, but you'll end up re-doing first year. You should speak with an academic advisor for details about the process, requirements, etc.

If you want to go to engineering at a different school, speak with people from that school.
