The class had a physics exam. Nothing hard at least if you’re smart and methodical. When asked how the scores were coming along he said that it depends on which problem and he even questioned whether or not we were there for a particular section. Later at night we had a lab and our professor helped us write the derivative function for finding a theoretical acceleration and left it with one last step for us to figure out how to simplify. He proceeded to say if we cannot figure it out then we are in the wrong class. After being helped by my partners on how to get acceleration variable by itself I agree. He usually is very laid back but I guess seeing how bad we are doing in general is taking its toll on him and making him agitated.
