Big question really is,
Do you know from passed history that you can actually study consistantly for upto a year without being physically taught, i.e. you do all the work.
Then have someone review it at the end ?
If so then DL is for you and I would recommend Bristol, but I am biased thats where id di mine.
If the answer was "No" you need to consider a modular Full time Theory Course at somewhere like London Met or Oxford. There are many schools that do the theory so research them all.
Good luck with the choice
