Best place to learn A/S level Statistics for Match online

I am doing a maths A/S level, and am doing the Statistics part at the momont (i couldn't choose mechanics).

The problem is thet thare is only one teacher in my school who can teach Stats (albeit not very well), and she has been off ill for over 2 weeks, and will probably be off wor a while, so does anyone know any sites that could help me?

Thanks in advance
