Superb. Well worth it.

We went from the light version to this very quickly after seeing what this app could do. I can imagine this app having value for many years to come. While I love the multi-student support, it would be nice to see an option for the teacher portions to be locked-out from students. (I dont think Sally needs to be able to see/edit Billys data, for example.)
