The system is easy to use, has many features for tracking students' progress. It was very flexible because it could be customized according to our needs. I really liked how easily you can share documents with other teachers or administrators if needed. Sometimes the interface was slow to load which made me think "I'm doing something wrong". This doesn't happen too often but when it does, don't hesitate to contact their support team as they are quick to respond! We have been able to improve student performance by having them work at different times during each day of the school year since we started using this program in September 2016.
