IXL is torture for us kids. Every time you get one question right you earn like 2 points but when you get one question wrong you lose like 10 points. This system has not made me learn anything useful. I would advise Khan academy since it's free and way more educational in many ways. Just look at all the reviews... https://www.commonsensemedia.org/website-reviews/ixl/user-reviews/child?page=1
