<p>Yeah this is extremely frustrating. When i said A i meant 93%+(should have been more specific), so the exam would have been at least a 24% difference. Also I agree there is a low probability of a flaw(though he is EXTREMELY disorganized). The fact that a professor can basically leave you in the dark for a majority of the semester then give you a grade significantly lower than another individual with the same scores without consequence is annoying to say the least.</p>
