>>1056449>>1056430University isn't free, even if it's free:
1 - it's generally only free once, so if you waste your free degree, then later find what you actually want to do needs a different degree, tough.
2 - when you are at university, you are not in full-time work. Much like you can't remove the front row of a theatre, if you miss out on 3-4 years of a career, the years you miss out on are the final, most senior ones. If you never needed a degree in the first place, that free degree could have cost you hundreds of thousands of dollars.
