I'm looking to teach Physics at secondary level or above within the
UK, yet since its been awhile since i've been at school, i have a few
questions, if anyone can help me out...


The keystages: 1,2,3,4 what age range do these refer to?? also does
GCSE's come into keystage 4 or is that taught after?

Am i to believe;

KS1 = 11yr olds???????????
KS2 = 12yr olds???????????
ks3 = 13yr olds???????????
KS4 = 14yr olds???????????
GCSE's = 15-16yr olds?????


Thanks.
