Final Grades

i don't think thats how it works - they have backup dates and everything. but im in a similar position, dont worry, im just trying to pretend theyre mocks in a couple months!

I'm currently a couple months from sitting in that exam hall for the real thing and I'm scared to death. My mock grades from this month consist of 9's and 8's but I'm afraid that I'm going to underperform due to pressure. If I skipped the exam could I submit my predicted grades?
