I am the same as many and am probably freaking out the most about English. As has been mentioned, the uncertainty of it all is slightly terrifying, and I'm trying not to linger on the scariness of it too much because I just become counterproductive.
In terms of post-exam discussion, I utterly agree with you, Yacoubb. Last year I went through all of the answers for the methods exam and even checked through my calculator history to see what I put down, and was pretty devo after realising all of the things I got wrong. Lingering on past tests/exams just gets me in a terrible headspace.
I just have to keep imagining how I'm going to feel on 18 Nov 5:15 pm to get me through. Not much longer now.
