Hi,
It will really depend on what the universities entry requirements are and what experience you have, have a look at the course entry requirements to give you more of an idea. Don't let being a mature student worry you though, that won't go against you. If for whatever reason you don't meet the entry criteria you could always look at an access course or a foundation year.
I commute to uni as I am also a mature student, and I haven't had any problems at all, I get along well with the rest of the class and really enjoy my time at uni. If you have any other questions about being a mature student I am happy to help.
Good luck!
