Actually Jonny, I am afraid I am going to have to agree with most of your points there!
I totally agree with you about getting a C grade, in fact if I saw the majority B's or C's in my results sheet, I would feel pretty bad...maybe it is because I have spent the rest of my education achieving A's and A*'s.
As you said, the pressure put on us to do well in our GCSE's is immense, its 6 hours solid at school, usually about and hour and home each evening, and then a huge study leave. So, maybe it is just you and me in this thinking, but I guess it's the pressure that has been piled upon to do well in our exams, that makes them seem like such a huge step.
(In fact, I had to retake my 2 maths modules, as I only (ONLY) got A's, and my maths teacher wanted me to get A*'s. Results came back, and I was one mark down on one, and 2 marks down on the other =])
But, I do have some major problems with revision. So many times I have sat down to revise, and every time I just get distracted, and go off to do something else. I sure hope things start to improve on the revision front!
Altho, sux for me, as I am currently having time off school for tonsilitus, at a pretty crucial time of the year :/ Sods law really.
Oh well, do let me know how you get on!
One more thing, what GCSE options did you take? And, have you selected your A level options yet?
