I have no intention to starting them knowing any magic at all. I plan to start them as "Cadets", the equivalent of 8th grade, where they first arrive and find out about the school while all being educated to the same starting point to begin their studies (as they will come from a variety of different backgrounds, so initally be at different education levels). They won't start to learn Cantrips/0-level spells until their first full year and won't be learning 1st level spells until their third year. With all novice players I think that I should be able to hold their interest without having to rush into the other spells - of course, more powerful magic items will still be fair game to also liven things up.
