Subject Choices

The way my school works I'll be going onto my S6 timetable in May, I know I'm definitely wanting to take Advanced Higher Art and Higher Apps Maths but for the Uni courses I'm looking at I need one Essay-Based subject with a B at higher or equivalent, I'm currently taking Art, Computing, Music, English and Regular Maths all at higher. I'm not really confident in English so are there any other Higher or level 6 Essay-Based subjects I could take next year that would fit with my current subjects?
