What's your idea of good GCSE grades?

Personally for me A* to B's but I agree that for someone less able C's are an acheievement and I'm always proud of my less able friends who achieve C's but for me I would be mortified if I got a C as I did in my English language after choosing the wrong question reference and sobbed for the whole of results day.

Do you mean that you answered a different question that you had stated?-If so you won't have lost marks because the examiner will immediately realise what question you did.
