Oh just got back the microbio test for mid semester, not very satisfy, just a pass...Total 34 people in the class, only 10 passed and the highest is only 71%. Wondering what is happening, is it true that the test was hard? I guess so, and i admit that it is tricky. However those Drs said that the test was easy, it was easy...argh...No doubt, because they are doctors and we are not even a bachelor yet. I guess they are setting the test harder, so that we can study harder for our final and also know what we have to focus on..good..-_-
