You get ucas points for level 3 qualifications... There's a list on the ucas website... They require a lot of study, even the ones like btec that get sneered at here and aren't something to do in 2 months. if you have a good language you could do a level 3 exam only in that without having to do any work... Not sure when the deadlines for exam entry are.
You could work harder, beat your predictions and try extras... Or see if anything you like comes into clearing.
I did a BTEC level 2 Key Skills award? (or something like that)... theres like 5 different ones you can do... and they forced us to do it in 1.5 days and I passed and I think its given me 20 UCAS points?
