First check the CBTF's accommodation page. If this will cover your needs, follow their instructions. Notice that the first examlet is early in Week 3 and the CBTF requires you to upload your DRES letter 5 business days ahead of time. So do this NOW.
Notice that solutions for lecture and tutorial problems are posted on the website, and the lecture videos have both captions and written lecture notes.
If you need other sorts of accommodations, please email your DRES letter to both instructors. It's usually not too hard to work out a plan.
If you have a disability but aren't yet officially certified by DRES, speak to them now. This includes not only physical disabilities but also problems that impair your ability to concentrate such as ADHD and test anxiety. Even if you didn't need accommodations in high school, you might need them for some courses in college. It takes a while to get certified, so start the process before you discover you need it for an actual exam or assignment.
