You don't. You use MySpace at home, not on someone else's PC and especially not if they don't want you to.
You could use the time at school to learn how to express yourself in English.
If you want something to do on a PC at school, you could set out to learn just how much damage you can do to a PC by being stupid enough to try and bypass security measures.
You could also find out just how much pain and hard work goes into clearing up the mess people do get into.
One machine I cleared out had nearly 100 separate problems - and we are not talking tracking cookies.
If, on the merits of your education, you do manage to get a job better than a shelf filler and have the use of a company's PC, trying anything as idiotic as getting past security could easily be grounds for instant dismissal.
