A levels/gcse resits

I’m doing A level Psychology,History and English literature.
I’m also doing an epq (mandatory by school)
And an re course (but I don’t think there’s an exam or anything it’s just a few lessons every couple of weeks)
I got a 4 in GCSE maths. (9 marks off a 5)
For universities I’m looking into doing Psychology/social work/teaching/journalism as potential careers.
I have the opportunity to do core maths AS level for one year. Apparently it will go really well with psychology.
There is November gcse maths and English resits.
Do you think I should resit gcse maths and drop core maths?
Or just leave my gcse maths and do core maths.
I was really proud of my four to be honest all my other GCSE grades were 7/8/9s apart from math but I’m worried if I do decide to do psychology my four won’t be enough for most universities. My maths teacher told me that my AS level will overshadow it and that Univeristies will be okay with my 4 in maths.
Side note: I also don’t like maths really and I didn’t have a teacher meaning I struggled to get that 4, there’s a little less then a month for the math resits
So should I do core maths or resit gcse maths?

It usually depends on the universities and what they'll accept grades wise. For social work and teaching, you only need a 4 in maths. Journalism might require only a 4 but I'm not sure. For psychology, it really just depends on the uni. For Lincoln, I looked at psychology in the booklet and it said that you have to get a 7 in maths to do psychology there. I would look on the UK careers government website because it lists everything that you need for careers that you want to do. Hope this helped - yr 13 student
