These pages are intended to help you. However, they do not save you from having
to do anything! Make sure that you make good use of them. Don’t assume that if
you print loads of stuff from this site, you’ve done loads of work -
Having said that, you may want to print this one out: it’s a pdf guide to the AS course, showing what’s covered in each unit and how it’ll be assessed.
Do check out the frameworks hub (in the links above) -
