If you signed up for a course (econ 1bb3) but it conflicts with your required courses are you still registered in that course? What i mean to say is it possible to do nothing about the conflict and write the tests and exams for the course?

I don't believe Mcmaster will allow you to do that as in won't give you credit

If you already selected it before today and do not plan to make changes, then you can stick with the conflict. Otherwise you can't confirm your courses if it conflicts.

If the exams fall on the same day, you will have to forfeit one as it's not McMaster fault.
