I'm panicking slightly after reading some other threads.
In my day we did 8 GCSE's, all in one year. I did no revision what so ever...and about an hours homework per night MAX. (Not all teachers actually set homework)
I understand things are different now. So; How many GCSE's to they take now? Over how many years do they take them? If they don't get an A when they first take it, can they take it again? How much homework/revision is normal.
