EAP 145 - YANG, Fan - Week 5 3/3

I am really unhappy today because my average lower 6%, and I think this should not happen.  I really confused about how teacher count our score and how engrade measure the average score.  Amber put the score like 0/10.  I don't know which section did she put.  OK, if I just assume it is in writing section which has the highest proportion in average score 10 multiply 30% just around 3 points.  Three points lower my average score 6%?  I think that is impossible.  Even I get 35/50 in my writing I can't improve my average score 6%.  I think that is extreme unfair.  Moreover, the NAA, IA, Bedfore works students put so much on them, and students even can't improve 6% in average score, I don't know how can this 10 points make my average lower 6%, and even it needs to multiply 30%.  Anyway, I am very unhappy today because I don't think it is fair even I know the rules are not only target me.
