What can i do with AAT book keeping?

It looks like you will be qualified to do people's book work. You will have to purchase a software package like Sage Accounting if you wanted to do this from home as this probably isnt included in the course fee. There are courses out there that offer a training course and accounts packages that you can do from home, so it all depends on what you want from the course and whether you are motivated enough to work on your own or you need a clroom based course to keep you motivated.
