Hello! I'll be entering second year in September and was just accepted into Honours Biochemistry (Biomedical Research Specialization).
I took math 1LS3. Math was always a poor subject for me as well, but I found 1LS3 to be very manageable and even easy as long as I did my work. If you don't plan on doing any more math in upper years and don't really like it, I encourage you to take 1LS3. Professional schools don't make a distinction as far as I know. 1LS3 really wants you to do well - they will drop your lowest test, the courseware contains last year's tests, the test questions are almost the same with the numbers changed, etc.
I also took physics 1B03 during the school year. That said, it is possible to get a conditional acceptance without it as long as you finish it by the end of second year. I found physics 1B03 to be one of the hardest courses in first year. I found math 1LS3 to be the easiest first year course. People are tempted to do physics 1B03 in the summer. But you should also know that everyone is scared of organic chem in second year (chem 2OA3, chem 2OB3), which you will be required to take as a biochemistry student. A lot of people take those in the summer before second year and you don't want to be doing that alongside physics.
As far as I know, the program is not math heavy whatsoever. The only further math course you're required to take is statistics 2B03, which is completely different from calculus. You can find the program requirements here: http://registrar.mcmaster.ca /calen...14/pg2432.html
Your electives are both supposedly on the easier side so that helps. I took health science 1PA3 and finished the week's work in an hour if I busy that week.
All in all, my recommendation is that you take both in the year. If you put in enough work, it is doable. Generally you will have to put more work in than you did in high school. What I found in my first year is that nothing was really harder
, but there was a lot more
you had to know. You also have to learn to manage your time because no one will make you work. Finally, ask for help if you need it. Seriously.
There's a lot of course reviews on MacInsiders so have a look at those. Might help you gauge the difficulty of the courses. Feel free to ask if you have any more questions.
