Hi.
I'm in Year 12 now - did my GCSE exams last year and did pretty well in them. Just wanted to say, congratulations if you feel the exams have gone well so far and I hope you can keep it up, and to those of you who've been for whatever reason disappointed with how they've gone, it really isn't the end of the world (that's a cliché for a reason!). As long as you've worked hard and you know personally that you've tried your best and couldn't have done any more, then the way I see it, the final result doesn't really matter.
Also, the feeling when you finish your final exam is great; seems like a huge weight has just been lifted off your shoulders and you can just relax for 2 whole months! So just make sure you keep going for this last part and then you'll be able to thoroughly enjoy your long break.
Good luck with the rest of your exams!
