Sometimes we catch mistakes on the exams that we've created. If you purchased a digital download of any exam, you will be notified of any changes to it through email. Whenever a digital exam gets updated, an email of the change is sent out immediately. Then, you'll be able download it again...*i*t's free if you purchased the digital copy.

For those that purchased a physical copy, track the changes listed below and update your exams accordingly. I update these exams as soon as I make the appropriate corrections, but because it's a physicaly copy, I have no way of informing you of the change unless you frequent this page.

Yes, even engineers can make mistakes, but hopefully, they can get ironed out. Thanks to everyone that has kept me on my toes with getting these updated. If you see an error somewhere, please let me know about it at [email protected]!
