The best thing about this program was being able see what my students are doing in real time as they go through lessons without having them email me back all day everyday! I also like how it has so many different options for creating quizzes which can be used throughout your class or just one at once depending upon preference/needs - even customizing questions if you wish too. There really isn't anything bad but there were times when certain things would freeze up such making changes not allowing us access right away etc... But overall great product!! We have been using upsidedlms since we started teaching our first year classes here last fall now going into Spring 2016 Semester 1 where new courses will begin next semester along side other existing ones already running from previous semesters including summer sessions. !
