I actually enjoyed doing the School Certificate. For the most part the questions were actually quite funny (the stupid kind of funny).
And for those who have massive anxiety issues like I had back then, just do it as best you can, take pauses to think about the question and you'll probrably end up with band 5/6's. If you think you're eligible for an illness/misadventure form then fill one in too.
I had massive anxiety issues with maths and I managed to scrape an 80 with an I/M form.
Have Fun, enjoy the freedom whilst you can.
Practice different ways to study!
All the Best,
