You should drop the course instead of petitioning to get rid of the grade, as you’re still able to do that for Yearly and Winter courses affected by the strike until Dec 31, 2018.

If you’re trying to petiton a Summer 2018 grade, then refer here: http://myacademicrecord.students.yorku.ca/academic-petitions

I would say to contact the Registrar’s Office at this point if you still don’t have your grades for courses that were affected by the strike.

Perhaps it hasn’t be approved by the course department yet? Otherwise, you’ll have to ask the Registrar’s Office about them.

YUFA has apparently filed for conciliation, from what I know of where they’re at in their bargaining with the administration. I have no idea if that will ultimately lead to a strike. I would hope not, but it’s too early to tell.

Why are you petitioning it when you can still request to drop a Yearly (17/18) course and get the grade removed?
