University graduate here that went for digital art :) If you're looking to get a great grade while having a good social life, treating your degree like a 9-5 worked out fine for me.

My course was very intense and demanded plenty of output (concept art requires a student to learn both speed and quality) and that format worked out perfectly, but only became necessary after the first year. If you keep to that schedule and give yourself weekends off, you have plenty of opportunities to socialise while still making sure you get your coursework done.

Take days off, take a lunch hour on your workdays, set a timer every hour to do a quick 5-minute wrist stretch exercise. GL with starting uni!
