HAHA ok well the Majority take them in Y11 and resits happen in 6th form.
All the older women in my family are teachers, Secondary, Colladge and Uni, believe me you know the stress you think your going through? Well it's nothing compared to the Teacher all kinds of **** the students never think off get's brought into it. And can lead to loss of a job, want a tip? Don't be a **** to the teacher you will get a easyer time.
Also just relax when it comes to the tests, seriously when you freak out or stress about them too much you flop around like a flounder on a beach.
