Place all files in SimCitySimCityUserDataPackages. If you already have the script files, you don't need to put them in there again, just the included package file.
If you start a new region, what I find I must do is start the region, save it, quit the game, and then re-start for any mods to work the first time, even other people's mods that I've downloaded here.
If you use this file, delete and replop any existing education facilities. Same holds true if you remove the file.
