It's not so much false as it is exagerrated. It's a well-written description of what the first year of law school feels like. These feelings are difficult to convey to everyone else, so he probably played with the details.
If he wrote that students study eight or nine hours a day, that probably wouldn't faze a lot of readers, so he wrote sixteen. The first semester, you will feel intimidated about the Socratic Method, even though few professors intentionally abuse it in order to humiliate students. And you might feel proud when you handle it well and embarrassed when you don't.
And the part about stealing books in the library - as far as I recall, that didn't happen it the book. One person argued to Turow that that's what people do. And some people at law school do get suspicious and paranoid, justified or not.
Fun book. There's a good reason every law school but Harvard puts it on its recommended reading list.
