I like how easy it was for me as an educator who has limited time in my day schedule to set up these tests! It also gave us results very quickly compared to other companies we have used before this one.
Nothing specific at all - just great tool overall!! Have not had any issues so far but always good when something goes smoothly :) Great way of collecting data from our students without having someone else do them or send surveys out etc.. Just by setting everything up myself took about 30 minutes total which allowed others to get back into class quicker too.
