Should I do a fourth A-Level?

Hii, I recently started A-Levels and did really well in my GCSEs (all 10 9s). Originally, I was offered to do a fourth A-Level but I rejected in thought that I would be doing an EPQ instead, and also I didn't want to spread myself too thin. I am currently doing bio chem maths and an EPQ, but I enjoy Maths and got a 9 in GCSE Further Maths, and also my teacher has been non-stop suggesting it to me so I was wondering if it would be worth doing A-Level Further Maths. Honestly I'm leaning more towards not doing it and focussing on work experience, other studies and my UCAT when the time comes. But some advice would be really valuable.

Stick with 3
Do an epq if you're passionate about the topic

If you want to apply for Maths, Physics, Chemistry or Engineering then you should take A-Level Further Maths.
