Oh... just got back my last assignment. I got 7x while the rest of the lab got 9x. I wondered what's wrong with my assignment. I look closely into it. It seems that I made nothing serious mistake. Oh, I found I didn't submit one of the answers out of the 4 questions. That's the reason why. I remembered just before I was rushing to meet LW. My friends told me that one of the answers was wrong, so I quickly changed it, reprinted and merged the answer for *that* quesion with the new answer. But somehow, I took out answers for 2 questions, one of it does not need modification. Since each question worths 25%, I got a 7x% while the rest got 9x%. I didn't feel that sad afterall. Mr BLOG
