in terms of med schools, canadian schools aren't very picky. american schools on the other hand, most require a lab component. L03 does NOT have a lab component. Whether you take 1L03 or not, I recommend doing 1BB3 to distribute your eggs among several baskets. Keep in mind 1B03 is noticeably harder than 1L03. If you think you can ace 1L03 take it a high mark is always nice... Also, last thing, some programs require completion of Physics 1B03 by the end of level 2 if you do a little planning you can figure out if or if not that'll be an issue for you (most likely not, most programs have enough elective room)
and L'Étoile i think we all had higher standards in high school
go easy on her.
