It's homework, but worse. It takes more than an hour to finish. It can build up stress on students who have an attention deficit. When you're done with it, it acts like you didn't even take that assignment. After that, you just learn nothing and get more dumb as you complete more lessons. When the teacher assigns the same homework you already did, it acts like it's a brand new lesson you didn't learn. This app is NOT mobile-friendly. Overall this app is just a poop scooper that is used to punish children. Idk why my teacher uses this and my grades are bad cuz of this stupid app my math teacher uses. IT MAKES YOU FEEL DUMB WITH THAT PASS RATE. KHAN ACADEMY IS BETTER.
