I work as a network engineer, evaluating products for my team. As long as you have peer review, you CAN NOT PASS! Students who don't understand the subject matter, or questionably know your language, should not be allowed to determine if you pass the classes! I KNOW my answers are correct. I've done this for years. It's so frustrating to not be able to pass because some students don't know what they're doing.
