Do AS predicted grades matter?
My AS are low and I'm capable of getting much higher as I have proven already in my biology exam.
Will unis care about AS Predicted grades?
Universities will not know what your AS predicted grades were but they will know about your predicted A2 grades (ie: the overall A level) which are determined by your teachers on the basis of what you get in your AS exams. If you surpass expectations in your AS exam results which come out in August then you will presumably be given predictions of equal or higher grades which will be shown to the universities.
However, a problem will lie if you were to be given low predicted grades for your final A2 year as these are what universities use to make their decisions. If you are not predicted the equal or above the minimum entry requirements for courses you apply to you will find yourself facing rejections.
As long as you are predicted high grades for your overall A levels then this is all the universities will see, along with your AS grades if your school certifies them. Your AS predictions are irrelevant.
