Keep schools from using Mathspace

Mathspace is a rather confusing as it works in the opposite way we are taught the subject. It is not nearly as forgiving as khan and is much harder to work with. Mathspace has more questions than khan in each assignment and if that wasn't bad enough, each question has a part A B C D and so on most of the time. It makes every single online assignment feel like a test a test that is worded horribly, as in once case one question included the word or 3 times in the same problem one after the other. It is not always clear what Mathspace is asking and does not forgive common human error or clearly ask what it is looking for. I am currently in high school and assigned Mathspace along with Khan Academy for "extra help" when all Mathspace has done to me and other students is confuse and frustrate us. Khan Academy does it much better and it doesn't only just teach math. You'd think with "Math" in the name they'd get it down but, questions are formatted in forms no students have seen before in class. This usually just leads to more confusion and frustration as it's almost always homework and getting the extra help you would need is not given. It causes a lot more people to fail than to pass. for these reasons I believe we should not be able to use Mathspace in school.
