I am coming to the end of year 12, however, for most of the year, I have had an awful attitude towards AS levels, meaning I am almost certain in failing all my exams and have taken it upon myself to restart sixth form. There is problem though, my head of sixth form is saying because I have not finished my BTEC Sport work that I will not be able to return and restart sixth form next year. She has only made me aware of this like a 3 days before we break up for summer holidays and I have many units to do. What I would like to know is; is she allowed to do this? I was under the assumption that access to AS level subjects was dependent on your GCSE grades? Any help or advice would be greatly appreciated. This is leaving me feeling pressured and stressed. I need to restart sixth form because I fully intend on going to medical school.
