Hi Khan Academy, I have noticed that many students do not like to use Khan Academy because of the hints. Mostly because they don't want to lose points so they don't use them and don't learn anything. I strongly advise you to not take away points just for using the hint. but if they use it and get the answer incorrect then you should. Instead, just let the class owner know that the student needs a little more help with the topic.
