Woah... lots of little smilies there.
It's only September. Keep that in mind. Your best bet is probably to work out a time-table and stick to it, although it's important to do as well as you can in your A2 modules as they're harder than the AS resits and you need to get them out of the way now. Just do a little bit of AS revision each night and you should be fine. You'll probably find that the units seem easier now you've done some A2 work. Good luck!
