Have the same problem at my school but im fight back lol
1)well if all u wanna do is visit blockled websites try googling "proxy sites" and use any one of the thousands of sites there are.
Jere are some examples
Hide My Ass! Free Proxy - Free Web Proxy - Free Anonymous Browsing
Guardster Free Web Proxy
Anonymouse.org
http://www.browser-x.com/
SpySurfing Secret Proxy
proxyz.be
there are literally thousands so chances r youll find some that ur school hasnt blocked yet
2) Go to ( at home)
Ultrareach
and download "UltraSurf 8 client", unzip it, put in on a usb memory stick, and take it to school and save it, then open the program at school, wait a little while and internet explorer should open with nothing blocked
3) if all u wanna do is watch videos at school, then try the google hack method
go to google and type: " index of (mpg|avi|wmv) The Simpsons " without the quotation mraks, the bits in the brackest specify what type of content your after, so u can change it to mp3 or what ever, the prat after ( The Simnpsons) is what your searching..so using this it will come up with
and download webpages where u can view what u want to...u can change the part in the bracked to just audio tracks and look for a specific song.
eg: index of (mp3|wma) Eminem
Look through the reults and find one the looks resonable, such as :
Index of /mp3/Eminem
You can right click it and select "Save target as" and it will download it
