Well, after I got the score of my 2nd term test, I felt very sorrow. I did well on question 1 and question 3, however, the question 2, I did very bad, even the worst. I know the question 2 was the hardest but I did not know that I only got that mark. I need more practice on the prove, also need to do well on my assignment.

There is no course this week which means I cannot learn more new things. However it`s a good chance for me to review all the study point. I need make sure I carefully read the class note and do more exercise that I can do to practice my skill. The final exam is coming, fighting for the dream!

From last week, the most important knowledge except proof(it always be top-drawer!) was the definition of O(n^2) and Ω(n^2). O(n^2) means the function that grow slower than n^2, on the contrary the Ω(n^2) means the function that grow faster than n^2. It`s not so hard that I can distinguish them easily. However, the prove of function f was O(n^2)(or Ω(n^2)) totally messed me up! The process of the prove make me feel that this prove was all made up by logic thinking and imagination. If you cannot thinking in right way, you might not get the final prove.I will try to prove the exercise and to make sure I can mastered the knowledge.

By the way I fell so good on my term test 2, there were two problems for me, one was the question 2`s prove, it seems that I could not prove it in convincing way; the other was the identification beside the prove, I just wrote some of it and I do not know if it will affect my score.

Wow! Second term test was over, it seems not so hard but I`m sure I cannot got all the marks because there was still have some tiny mistakes in my proof. Compare to 4 weeks before, I am sure I grasped the point of the course and now I am not so confused about my future. wish I can got a good mark in term test 2.
