I would not do this due to the fact that your teacher finds out, they will most likely give you a detention, lower your grade, or worse. Also, it may be impossible to tell you because your school may have a firewall that once if figures out there is a way around not being able to tell you, they will then block that route. Therefore, I recommend just playing it at home.

If you mean is there a site where you can play Bloons Tower Defense 3 at school, or other places, that have a protective filter, the only site I can find is coolmathgames.com or englishbanana.com. If your school or work has these filters, they are there for a reason, and you are obviously not meant to be playing games on them.
i dont think you can
