S-cool is a good revision site, but only has a few subjects, it only covered one subject i studied, but this may help you.
See the related link for THE BEST WEBSITE FOR A LEVEL REVISION NOTES.
The BBC bitesize revision website is always the best. You can choose what you revise that is relevent to your topics. Thats what I used, I now have an honours degree in science and start my PhD later this year.

There isn't any good sites that gives good advice. The best advice is to get the information in person from a good person that you know and trust. You can go into a chat room or Facebook but they aren't good sites for advice.
there is ask.com i asked it where is Egypt as a test and it came up with a bunch of sites about Egypt pretty good but this sites still pretty good as well
