Ya know...that's not right. Accounting rules change every few years. And with tax accounting, those rules change every year (but I'm guessing all you've touched is book vs. federal tax differences..and I don't think those have changed within the past 10 years). So if all you're going by is what he's teaching in class rather than what's in your textbook, you're going to mess up on those exams, unless the exam questions are 10 years old too.
