Both the undergraduate calendar on the registrar's site and mosaic's planning app are not quite sure which courses are actually being offered. The only way to tell for sure which courses are offered is through the timetable on mosaic. I have a short summary here, including descriptions:
Courses offered in 2015-16
Physics 1C03 - a course for people who care about physics*; requires Grade 12 physics
Physics 1CC3 - the course after 1C03; requires 1A03 OR 1C03
Physics 1A03 - a course for people who only need physics to get into med school (or other ulterior motives)*; does not require Grade 12 physics
Physics 1AA3 - the course after 1A03; requires 1A03 OR 1C03
Physics 1D03 - a course for engineers (approx. equivalent to 1A03/1C03)
Physics 1E03 - a course for engineers (approx. equivalent to 1AA3/1CC3)
Physics 1X00 - a course for people in the physics program; it doesn't give any credit, but it's a program requirement
Old Courses hanging around the system
Physics 1F03 - this is now Astron 1F03, but it's sometimes still labelled as Physics
Physics 1L03 - a substitute for Grade 12 physics
Physics 1B03 - the old 1A03, except it required Grade 12 physics
Physics 1BB3 - the old 1AA3
Physics 1BA3 - the old 1CC3
*note - this is a very blunt way to describe the difference. There used to be a note on the physics and astronomy website which said that 1C (1BA3 at the time) was for students in physics, chemistry and math and 1A (1BB3 at the time) was for students in biology, neuroscience or psychology. Maybe that's the more politically correct way to say it.
Personal note: I took 1B03 and 1CC3 last year. (1A03 is basically the new 1B03) The 1C courses are much, much better than 1A. Even if you only need physics to get into med school, if you enjoy physics, you should still take 1C courses. You need to take 1A03 if you didn't take Grade 12 physics, but you can still take 1CC3 after 1A03. Also, Dr. Karen Hughes is absolutely amazing. Be warned though, she will give you your money's worth so it's probably not the bird course you were looking for.
If anyone reading this knows how to update these websites... please, please do so because people are missing out on physics courses. (The reason I accidentally took 1B03 last year was a website mistake)
I have asked a question at askMcmaster; e-mailed
[email protected] master.ca and asked in person at the registrar's office. I have not gotten any answers. I went to the department of physics office and asked; they promised to do something, but I may have to go bother some more people.
Also, if I've made any mistakes in my list of courses, let me know. I'm pretty sure I have things straight, but my sources are word of mouth from various professors and staff in the physics department and bits and pieces from the registrar's site and mosaic.
