Year 11 Maths, Further maths, Physics A-level combo, any advice?

I am a year 11 student who is currently deciding what I want to do for my a-levels. My main interest is maths (obviously) and im predicted a 9 in maths, and im also taking FM gcse in which im predicted a high 7. I have received an 8 in physics and am predicted 9. I am just a little worried that this combo will be extremely difficult, and that I wont enjoy physics. It is myfavourite science, however im not as interested in it as I am in maths.

I am planning to potentially do an engineering degree or a maths degree in future. Does anyone have any tips/advice for this combo? Thanks to all who reply.
