Necessary revision for Business AQA Studies A-Level May 2015

Does anyone know of anything that I specifically could be revising, so what hasn't come up in recent years, or anything that hasn't been asked before, for all 4 of the BUSS AQA exams.

I do a 3rd year at college and I've really only picked Business up as a time filler for my timetable, as I have my priority on my Law A-Level.

I'm not too fussed about what I get in business, but anything better than a D would be great.

I'm struggling to know what to revise, any help on this is massively appreciated!

My teachers for Business suck, one is constantly off ill and the other gets us learning one definition in an hour and a half, so I rarely go in and try to revise at home myself, but struggling to know what I'm potentially looking at in the exam.

Any points that are relevant on Business studies are relevant here.

BUSS 3 and 4 annoy me a little as it includes your own research. I didn't enroll onto the course to do my own research, I enrolled to be taught the components of the course.

Please help

Thanks
