In the ET school they seem to get bombarded with religious craziness from all corners of the globe and not just our own homegrown variety

You'll find that people put their kids names down for 2, 3 or 4 ET schools in the hope that they'll get into one. Like, we had our fella's name down on two because we weren't sure where we'd be living in 3 years time!
