I like that it allows me to see all of my students in one place, including their current level/grade as well as what they are working at right now! It's also helpful when you're looking up information about your student since everything can be seen from any page (ease).
The only thing i dislike with this program so far has been how slow some functions seem compared to others - such things include loading new dogs into an existing profile or searching through profiles by breed etc. But overall great product!! There really isn't anything bad to say- just look around online there will probably several reviews if not more than 1 other person who dislikes something else but nothing major yet anyways good luck :).
