I'm back from a bike ride, just a 45min blast around my town and the surrounding forest. Not much but I can't stand being inside all day. Now sweating like a pig in a sauna but hey.
How you feel coming out of an exam means sod all from what I have experience, I have had 100% in exams I felt unsure on (triple physics when we had a crap teacher.) and B in RS gcse when I felt confident that I had done brilliantly (its a joke subject.)
Even then you are at the mercy of the examiners, AQA philosophy AS I have yet to speak to anyone who got above a C, we were all confident and predicted B's and A's however they used us to stop the press having a go at "exams being easier" and marked them incredibly harshly.
