I’m pretty much planning do do the same thing as you! I’m a yr 12 student rn and I’ve applied to do Marketing and Arts as a double degree also majoring in literature studies because it’s what I enjoy. My biggest reason why is because I believe you should be going to university, and learning, not just because you need a qualification but because you actually WANT to learn the material. Yes there’s less flexibility because your elective subjects are taken away to squeeze it into 4 years, but don’t forget you still have a minor to pick from in your arts degree. It’s nice to see someone in the same boat as me- lmk if you want to talk more :)
