IXL's point system is painful. In the later stages of tasks, when you get a question right your 'smartscore' (which I think is a pretty stupid name. It suggests that your intelligence revolves around this one revolutionary task that you'll forget about in 5 minutes) Increases by 1 or 2, but if you get a question wrong it decreases by 7 or 8, putting you back as much as 8 questions. I hate it. Do not recommend. If your teacher is putting you through this, file a court case for child abuse. I send my prayers.
