If you're at school and you get something wrong on a work sheet, the teacher can tell you how you got something wrong and let you know so you don't make the same mistake again. And if you get it wrong by yourself, you won't really know how to get it right the next time. In addition, they say that it's also better in a classroom because the teacher wants you to succeed.
