The same as us. However, students who gain the A-level this year (either in Year 12 or 13) do not have to sit Units 1 or 2 to gain their A-level. Yes, your school has to sign a form saying that you've covered it but you don't have to sit the exams. I have that straight from the WJEC. It's the same for anyone doing A2 FM too. ie They don't have to sit FM 1,2 or 3 this year.
