My A level exams are coming up soon and this sounds stupid but I've not passed my gcse maths yet because I've never been able to remember any of the stuff I revise and I just shut down because of the stress during the exam and I have this last chance in the form of 3 papers with 2 being calculator coming in about a week and I'm terrified that I won't be able to pass it and have to finish secondary school without a maths gcse and this may harm my chances of the uni I got a place in taking it back because of this. What should I do?
