Dang, if money isn't plentiful, there are way cheaper options in NA than that. A good school can definitely help you network with future successful people and to some orgs the name on the diploma can help open some doors, but the degree is less needed nowadays than it's ever been.

It covers 2 years of tuition and a bit of living costs in UK. However, I’ve now lost financial support from my parents since I can “just earn it yourself” and I’m in no hurry to go into debt. Will probably work part time during the first two years to cover whatever is missing.

that's smart. Working while going to school sucks (that's what I did), but not only is graduating without debt a fantastic feeling and great economic position to be in, but it also made me optimize the monetary consequence of my choices a lot more. When you don't have to pay it off for years, it's very easy for your mind to convince you that you need a new laptop, or a new car, or a generous nightlife budget, etc. Even just new vs. used books makes a big difference in cost.
