Maths vs Psychology A level

Hallo,
I’m choosing my A levels very soon, and I’m torn between Maths and Psychology. I’ve wanted to do Psychology ever since Year 8 (I was and am very interested in it) and was excited to take the A level. I also had a taster session in my school, and I enjoyed it. However, I have been told that universities don’t care for it, and I won’t be chosen for my universities of choice, and be dropped in favour of people who do more “valuable” subjects. I do like Maths, and I’m in the top set at school and get good grades, which means I also take Further Maths for GCSE. But I’m really not sure I like it enough for A level, even though my parents say that it’s the only sensible option.

So I don’t know whether I should go with the subject I personally find more interesting/fun but have never done before and isn’t worth anything on applications, or a subject I am already very good at + can achieve high grades in and is far more respected, but may not enjoy.

Whoever told you that Psychology "isn’t worth anything on applications" is talking absolute nonsense. What course would you ultimately be applying for at uni, and at which unis?

Hopefully either Psychiatry or Pathology, but either way I’d be going to med school. Which is why I would choose Biology and Chemistry as my other two A levels (we can only do three.)
