I am appealing to drop this course CLST203 after the deadline because I have failed the midterm and I was able to view the grade today which was 2 days after the drop deadline. There is a extremely high chance of failing this course after this grade since it has a weight of 50 on the final grade. During the weekend when the grade was uploaded I did not get a chance to see it since I was in Toronto taking care of my grandfather after/post operation.

Please advice me on what to do next.
