First, a couple of notes:
The game will only run on a Windows machine (Win 7 or 8).
Depending on how fast the computer at your house is and your internet connection, you may get lag.
The MinecraftEdu virtual app is about 220mb in size, which is kind of big. Make sure you have permission to download the virtual app before doing so.
ALL activities on the server are logged, even when you access the game outside of school.
The game periodically backs itself up. If something gets destroyed, please let Mrs Jacobson, MrMantz, or MrSeybold know.
