Where to get school work to do at home from?

I'm 14, and in year 9, KS3. Recently I have been physically and mentally unwell and also in hospital. Anyway, that doesn't matter, basically I'm physically unable to attend school at the moment (I'm waiting to be loaned a wheelchair from the hospital). But I need some schoolwork to do at home, (my school won't give me any) and was wondering if anyone knew of any websites where you can download work sheets/tests/quizzes ?? I'm just so bored!! My GCSEs are coming up and I really want to do well but I've missed a lot of school!??! Please help and thank you for reading! Thanks in advance xxx
