mate unless ur loaded which im assuming ur not i do not recommened moving to london to go to uni. dont get me wrong this place is amazin and has some of the best universities in the world but its sooooo expensive. I live about an hours drive away from london but am soon leaving to study in portsmouth at portsmouth university. Id love to study in london but i cannot even think about it. I would definatly consider more options and get in contact with a few unis outside of london as they will help you and give you alot of advice on accomodation and finance. As for your qualification i have no idea, again the universities will be able to help.

I will be looking at around a £20,000-£25,000 debt after university outside of london (portsmouth) for the 3yrs i plan to stay there. That includes tuition fees, accomodation, food, drink and not forgetting weed money. You need to research alot more

The north tends to be cheaper than the south thou, not sure why. Gd luck!
