You are still a minor under the age of 18, so yes.
As I stated, the administrator of the network has obviously prevented downloading of torrents as they are usually "legit", so when the police raid the school for downloading tons of "legit" software.. who gets the blame?
Also, if they provided you with a laptop, it does not make it your property. If you rented a car for a week, you can't return it with a new body kit on it. It does not belong to you and you should not treat as such out of respect.
As others have suggested, use Wi-Fi in other places to download games / torrents. Why do you always need to do it in school?
