Quill will mark you down for the tiniest mistakes. If you make 1 spelling mistake, then you get it wrong. I am a student and I want to get a 100%, so I have to keep going back, and back. It is really not fun and really angers students. It gives us anxiety and can be way too time consuming. I am a fifth grader and I would definitely not recommend these to assign to students like me. Never, never, never use it!
