I need a formal and non-aggresive way of confronting a teacher for his test.
So this starfish teacher told me that only buffers, pH, and solubility was going in the test. Today, it was taken by a substitute because he "had to run an errand". Mother forgeter took salts in the test and not just any salt. He tested on ammonia and ammoniac. The two hardest salts in existance. And not only that, to do something with them, you need to know the concentration of either H2O or OH-. He didn't give stuff. I did what I could by guessing but this test counts like 40% of my grade and it's supposedly an "easy pullup".
I am furious enough to violently murder him if I see him. How can I calmly and formally talk to him about this situation?
