All the professors I had didn't accept that I have already solid notions about the arguments in their course. I tried to explain I worked in some agency and they invested in employee knowledge but the tilts was embarrassing, they mocks you but systematically when you hit the highest score in the test they compliments for "how well I've studied" when I didn't spent one minutes on studying while I was engaged with more complex and training exams. I wish a degree where you can attend the exam without following the course if I'm already prepared.
