I don’t know if I should do psychology for A-levels Watch
english lit's a lot of work but don't let that put you off, all a levels are a lot of work.
all your choices would go well with one another- perhaps if you wanted something a little more academically rigorous pick english lit but i don't think not having english would hinder you from doing art at university. pick film studies if the subject appeals to you more.
pick subjects you'd enjoy so you'd be willing to put the effort in.
