our school has this RM filter thing which blocks a load of sites like games and videos and things. Is there anyway to get past it?

Why dont you try and actually get an education at school and go on video and game sites when you're at home.

Pity you don't spend more time LEARNING rather than trying to waste school time and equipment trying to watch videos or play games which you can do at home in your own time...and before some clever dick accuses me of not answering the question,
Yes there are several ways to get round those filters none of which am I going to reveal here.

Why don't you put as much effort into learning as you do into trying to get to your games and videos?
