Extending for 1, 2 or 3 months with a Fench course?

[SADEMA]

hey guys! yes sounds quite stupid! Learning french in the UK???

The thing is that I've just finished my MBA in London but my visa expires at the end of Oct but still need 5 more weeks in order to have 800 pounds during 3 months in my bank statements and be able to apply for a PSW permit.

So one of my options is to extend as a student for a few months, but just in case I dont get the support from my University I wouldn't mind to pay for a short-term course. But doing an English course, even a Business English course, would be a waste of money and time :) not to show off, but come guys I did an MBA, give me some credit B)

so if anybody has any good advice I'll be more than glad to know about it

thanks in advance
