I'd be inclined to recommend going with a technical course because you'll be given proper projects to develop and work on, and often you get quite a lot of flexibility in terms of what exactly you make so you even get that freedom of making something you're passionate about. Having that kind of structure will really help you to put together some great work for an eventual portfolio as long as you're made of the right stuff, and will help prepare you for the 9-to-5+ structure of working in the industry rather than when you feel like it.
A more theoretical course like art history will give you a lot of great knowledge but not a lot to show for it — and motivating yourself to work on significant personal projects might end up being harder than you think when you consider how much time your Uni course and social life will take up. You'll also learn a fair amount of irrelevant things, whereas you can fine-tune what you learn more precisely if doing it in your own time. Also, technical courses often have you do historical research anyway, just like an industry job. You're not expected to just know exactly how X from Y period in history should look, what every art movement has been, etc. ![]()
Another thing I noticed is that almost every single person who did the art history/fine art/etc courses at the art and design college I went to are now working in pretty shitty irrelevant jobs, whereas those who did the technical courses like me are doing much better. That could just be coincidence but I don't see people doing those courses getting very good returns on their investments.
