This website sucks especially when your teacher assigns 31 of em due in a week with 5 questions each. For it not to load and count correct answers as incorrect. Its just straight useless and doesn't help you learn. Teachers use this because teachers now-day don't like to teach you and just assign busy work and sit and watch tik toks and there phone. Teachers please dont use this and just teach your kids. This is why our generation is gonna end up homeless.
