I am 27 and have completed a HND and a full degree to become an engineer. The one thing I would recommend to anyone considering going to Uni is to find out whether you need a degree to work in your field. There are far too many people who are entering the workspace with general degrees in'Business Studies' or 'Media' degrees. These general degrees are, generally, not needed by employers. A lot of my friends who went to Uni to undertake degrees in non-cognative degrees, as mentioned above, are not using their degrees in their current employment. This means they have paid £1,000's for nothing.
In my opinion undertaking a degree in photography would not be beneficial as it is an art. Where as if you were studying a science you would require a degree to understand your work. To put it another way, no one cares whether Banksy has a degree in art or not, but you would bloody hope your phamacist has a degree before dispensing your medicine!
If you are seriously interested in photography as a career apply to studios as an apprentice and see whether they can pay for you to do a vocational course in photography. There would be far more experience to be learnt on the job than just solely in the classroom.
