What do I choose for my A-level choices?

I am doing my A-levels next year but I have to choose what subjects I want to do before January. I know for definite that I want to do Biology and Psychology (I'm predicted 9s for both) but my issue is I don't know whether to do Maths (predicted a 9) or Chemistry (predicted a 9).

I find maths very boring but I'd say I'm quite good at it. If I did maths i'd have to do psychology at another school (not ideal). I'd do an EPQ regardless of whichever one I choose. I like chemistry and am good at it (and in general people seem to enjoy chemistry at my school); maths is a little easier for me, but I'm afraid I'll get bored of it. I know I shouldn't choose based on teachers but one of the teachers in maths is extremely boring and I have had him for the past 2 years, so the idea of having him for 2 more years puts me off it (only a little).

I think both are good choices career-wise because the universities I want to go to accept both combinations although I think maths has more options for if I want to choose a different course. I want to do something biology-based, possibly neuroscience or biopsychology. Anyone who does both maths and chemistry, I'd really appreciate some advice on which to choose.

I had my heart set on doing biology, psychology, maths and further maths but I realised further maths is basically irrelevant, and I know for sure I will get sick of it, so I changed my mind to doing an EPQ. I am very confused so I might talk to my english teacher because he is completely indifferent and has children who have gone through this (and I don't hate him like a lot of the others), but I wanted to see if I could get any form of help from this.
