not the course im doing you couldnt its a full time course, all are that i know of.
I think you would be able to get an adult learning grant. A bloke off my course last year saved up enough money to rent a room/flat, pay for tuition fees etc etc and when he applied for college he found out about the adult learning grant thing and they paid for the whole lot.
I dont really have any info on it so you'd be best off phoning up one of the colleges and asking for some leaflets and that.
