Al level maths or psychology

Hiii 🤗. I currently do psychology in highschool which I just finished my GCSE exams on it (stressful but yayyy). However. I still can't decide whether I want to do a level maths or psychology. I like maths. I genuinely do but I feel like after a few months I might lose interest or not feel smart enough as I got into a really really competitive college. I know that with lots of effort, I can get an A or A*. However what if I can't? I also enjoy psychology and I have a mini headstart as I just finished doing it. I already chose Biology and Chemistry. I really really don't know what to do as I have to make up my mind by September. Help meeee plsssss

Well you can never really know how well you do in either Maths A level or Psychology because it will be very different from GSCEs. If your school does taster events of either the subjects, I suggests going to them because it might give u an rough idea of what it look like. Personally, I really like studying Psychology. You learn like different topics of psychology which are all interesting and if u understand it, its quite simple.
