the first exercise class today is awkward I just finished the first inventory exercise class and I am shocked. The research assistant only taught for 40 minutes while the class should be half and 1 hour. I prepared for the exercise for 2 days and did all the calculation personally. She flipped the slides so quickly that I can't catch up with her. We students don't have time to think and input on ourselves. She is pregnant and I know that must affect her professionality. However, she was not doing her job at all and this behavior breaks the bottom line. Hope next exercise will be better.
