I did Critical thinking as an AS in Y10, since my school wanted me to do it as a side subject, and basically every Wednesday, I would stay behind with a few other chosen students and have a teacher (teaching us for free/AKA Also my PE teacher) teach us Critical Thinking. Main point was to develop the skills. However, in the exams, since we were more focused on GCSE's, we flopped our Critical Thinking AS Level, and I got only a C.
In Sixth form I am doing Bio, Chem and Eng Lit btw.
Will this damage or make it impossible for me to apply for top Russel Group Uni's as I have a C in an AS/A level. I know I did bad (the other 4 students failed and got U's). Is there anything I can do to fix this issue?
