There are a number of universities that don’t require any specific A levels. Manchester just specified AAB in any three if I recall correctly.
That said, you’ll probably find that the course is less of a shock to the system if you do English language, psychology and biology and maybe another language to AS if your school offers that.
You might be surprised to find, though, that subjects like history and geography can be beneficial. Geography is good for understanding epidemiology and so forth whilst history can equip you with analytical skills that can be really helpful for when it comes to going over case notes and so forth. Likewise, art will come in useful if you’re any great shakes at it when it comes to producing resources. Maths will be great for helping you understand stats in the deep way that most people on the course never get around to.
Bear in mind that you’ll be taught psychology on the course anyway and you’ll be given a crash course in linguistics when you start. You’ll never get another chance to study things that are purely your choice as well as preparation for a career. So I’d definitely encourage you to make a choice based on interest as well as studying required subjects.
