take grade 12 physics in the summer
take 1b03 (and 1bb3 if u r interested) in the next summer (2012). depending on how comfortable u r with physics, u can take it in the school year or summer 2012. the reason i recommend taking physics 1b03 in summer is because I FEEL its a lot of work and boring (i m more into bio and chem than physics). if this applies to u too, i strongly recommend taking physics 1b03 (and 1bb3 if u r interested) in summer 2012. u will do MUCH better.
also, speaking from experience, there is not a single AMAZING prof teaching physics (they are good but not amazing). if u take it in first year, the two profs are hughes and wilson.
i dont much abt wilson, except that she doesnt have an accent
hughes on the other hand is a professor THAT IS NOT FOR EVERYONE. she doesnt give out notes. her teaching style is like of story-telling. if u r not comfortable with physics concepts,
dont take it with her. and dont think that u will adapt to her style...reading the textbook is VERY boring and will discourage u in so many ways.
that being said, u can also take it in second semester. one of the profs is rheinstadter. he is very very good, and very approachable, and very helpful as well + he gives out notes!!!
dont overestimate urself and expect urself to be super in everything. u have to learn so much in SO LITTLE TIME. i m talking abt the transition to uni from high school. i was a 90% student in high school, came to uni, marks dropped because i overestimated myself and loaded my courseload with lots of hard courses. and i didnt end up doing so well.
hope this helps u in ur decision making.
