The Final of The BIology Experiment

I think the biology experiment is the most difficulty course in this semester. It has to do experiments and make a report which is about the experiment. In the medial semester we have to make a big report. In the period of making it, I often slept when it was 3:00 or 4:00. Then in the ending of the semester we have two final of the biology experiment. One of them is a written exam and another of them is to see the samples and to write the answers. Then the final occupy 40% of the grade and the most important experiment only occupies 20%. It make me feel strange.
