That's a good place to study. With IT its hard to give advice, that course will open up a lot of graduate programs and for a lot of people university is one of the best experiences of their lives, with the potential to develop new skills, insights, professional and personal networks and potential business partners, 25 is really not that old to start uni.
On the other hand 4 years in IT is a long time, you can do a lot in IT in that time, you will have to sacrifice comforts like steady wage and disposable income.
I think that you have already made the decision to study, its not like you are committed for 4 years, if you hate it you could leave even after one month, but I suspect you will probably enjoy it massively.
