Search Results: make myself look better

Hello, everyone! I'm 17 years old and a sophomore in college. So, today, I checked my transcript and I failed college trig with a C-. To me, it just doesn't feel like I failed and I should of received at least a passing grade. I would usually be disappointed with myself with me failing a class, but I'm not because I know it's the teachers fault. There are multiple reasons why I'm blaming the teacher. 1) she actually did not teach us anything. Her class was just based on students teaching each other topics (brand new topics) without any lessons beforehand. 2) she might be holding grunge or something against me because I noticed my grade is close to passing. When I checked my grade on my final, I somehow received the exact same percentage on the last 2 tests (58%). Which is weird because how did I get the same exact grade twice. She also drop one of the tests if you do better on one of them. So, I don't know she tried doing this to not make me pass. 3. the class averages. Looking at the last two grade percentages, I was just astonished how bad the percentages were. So, on test 2, the average grade was a 53% and on the final, it was a 49%. With average grade percentages like these, something is going wrong with the teaching. Not only that, some of the stuff she assessed us on the tests, some of the stuff was never shown to us beforehand or given to us in the homework and hell, not even the textbook. Also, she's super unclear what she wants us to do and didn't tell us to do it in the question. Like for example, she told us to have a worded conclusion on proofs although she never told us in the question nor in class beforehand. So, today, I filed a complaint against the teacher for unfair treatment and going try to see if I can get my grade appealed. Do you guys think it'll go far and I can appeal my grade? Also, here are pictures of the average grades on the tests to prove my point.
