I assume that you are being blocked at school and so the answer is: You don't - you do some school work. (You may even learn how to spell and punctuate.)
If you were at work and you attempted to negate your employer's computer security that is often considered to be Gross Misconduct and grounds for dismissal.
As you appear to be at school, take it as lesson about the real world. Get used to it.
