Khan Academy needs some changes…

While Khan Academy may seem like a good learning tool-which, at times, it is-, it can sometimes be a problem with math. When you don’t understand a question, it urges you to use a hint or videos. And then when you do, it marks it as incorrect if you use a hint. This should be changed, as a student might struggle with a question, and then decide to use a hint. If they do, it becomes marked as incorrect. This is annoying, and sometimes more than annoying if the assignment is graded. Then you have to do the whole assignment again. I suggest the following: this should be changed to if you use two to three hints in a row, it becomes incorrect. It shouldn’t be marked wrong because you need a hint once! So to the higher-ups in Khan Academy, change this, please.
