Actually Switch is considered rather bad.

This looks rather a lot like `$school = $ARGV[0];` or maybe `$school =
shift;`.
In any case, your problem is that `==` is numeric comparison. If you had
warnings turned on, as you always should, it would warn you that you were
using a non-numeric value in a numeric comparison.
`eq` is the string/lexicographic comparison operator.
