I am currently working on my university degree, 1st year biochemistry student. I know a lot of biology students (some within the animal science program) that have to deal with both calculus and physics. Both these courses offered for the 'bio stream' students are not as difficult as the courses taken by the physical science students (which I am involved in). There is a lot of support and help for these students and most universities have help rooms. I cannot speak for all campuses though. Good news is in most programs after first year...all math and physics courses are non-existent.
I recommend taking grade 12 calculus and at bare minimum passing the course. University calculus is nothing like high school, with studying and effort it can be conquered.
