help w alevel choices pls

hey im in yr 11 and i dont know what i should pick for my alevels. i wanna be an art director in the future and im very very sure that im going to pick art for alevels, but im not so sure about what else i want. I took art for my gcses along with geography (parents picked geog for me), and i suck at geography. im thinking about taking media or like english lit or lang (ALSO now that i mention it, can someone tell me which eng would be better and more rewarding to take pls) and i wanted a fourth subject but im not really sure. i also dont get what the alevel terms are like btecs and whatever else there is.
im not too sure if i want to go into art directory too. its a job that feels like it was made for ME because im a very creative person and i can allow my visions to become real and everything AND get paid for it. so if anyone knows any high-paying art jobs that include directing, being creative, being free to work flexibly etc etc, please lmk !! also if you're an art director please give me advice on what i should do and what you do for work !! fat paragraphs i know but thank you for reading )

Id look at the courses on some unis websites to see if they specify any particular subjects at a-level.
If they dont specify any in particular (i.e. they just want certain grades) then pick whichever subjects you enjoy the most and think you will get the best grades in.
