As far as I know you need to take Grade 12 Physics to take 1B03.
You'll have to contact the Associate Dean's office about that. You can email them at

P.S why would you want to take it during the summer before you start your first year?
Honestly you should take the time to relax and enjoy sleeping in and your daily activies because once first year starts you're going to get blown off your chair with the amount of work you're going to be getting.
Especially if you're in life sci - it has one of the hardest first year programs.
I was a 95+ average student in highschool and got my but whooped this year ... so enjoy like while you can before mcmaster steals it away from you
