Only because it could teach students that things aren't always easy, sometimes you need to do most of your learning yourself, even when someone should be guiding you.
Either it could develop grit and determination, or the children could decide to just give up on their education. I've seen many students on both paths.
A lot of the staff run things poorly. I didn't get my schedule until the actual first day of school. When I did, it had mistakes and I had to have it changed multiple times. Teachers were getting suspended, fired, and quitting all the time, too, which really disrupts our learning. Many teachers don't do a great job, either. A certain teacher wouldn't let anyone finish a 50 question test, when most of the class didn't even get half of it done. We had only one 50-minute period to take the test. This was an advanced honors class, too, and was for high school credit.
Bottom line is, this school deserves its 3/10 rating. If you have another option, you might want to take it.
