Query: Give me "Welcome Back, Kotter!"

As someone who is slightly familiar with public education, I found this book to be a source of nothing other than rural sap. I thought I was getting an insightful effort, but what I got was cliche and mindless nothings. The writer has a flair for the obvious. That's about all I can say about this book. I tried. Little engaged me and that's what I look for in a book. Sorry. Next time, I'll just buy one of the standards, like "Up the Down Staircase," or "Blackboard Jungle." Spine is below that standard. By a country mile...
