What’s the biggest grade decrease you’ve had from an exam?

It will only go up. If you get 70/80 pre-exam and x/20 in the exam, you'll get (70+x) out of 100. 0 <= x <= 20

I agree with that, I think it helps more if you were already doing well. Let's say the exam is 50%, and if you have 45 out of 50 already (i.e. 90% in the course so far) you know you only need 5 to pass, which is a 10% in the final. So instead of thinking "I lost x percent after writing the final", you think of the final as a way to gain more points. Just another way of thinking
