I am exhausted now...It is almost midnight but I have no idea about when I can go to sleep.
About Week 10, all I remember is the quiz about big-Oh expression. That is fairly simple I would say. And about Week 11, totally nothing.
The reason is simple: I went to USA for a short trip during the weekend of week 10, which is connected to the Fall Break on Nov 17 and 18. I was supposed to arrive in Toront on Tuesday by bus, but I was stuck by the blizzard around Buffalo.
That was terrible. We were stuck five days. I just arrived in Toronto yesterday afternoon. And I have been busy on everything I missed this week: lectures, assignments, and even a test.
Hopefully, I can write this blog as usual next week, or more than usual, given that next week will be terrifically harsh for me. I have one assignment due tonight which I have just finished, one for tomorrow afternoon, one quiz for tomorrow night, another assignment due on Tuesday, a term test on Wednesday and another two assignments due on Thursday and Friday. God bless me.

Week 9: Term Test 2
-I feel like that there is correct calculation in my solution of Quiz 7, but I am afraid of the format. I did not use the Sigma notation. Hope that won't hurt too much.
-I missed two lectures. It results in that something in the lecture notes are hard to understand by myself. I guess I have to ask Adam after the next tutorial.
-Test 2 was not difficult, nor easy. I made the same mistake: writing too slow. This time I finished question 1 and 3 first, and left little time for question 2. I was nervous because of that situation and this disturbed me. I ended up with not finishing that question. Ironically, after I breathed the fresh air out of the test room for a couple of minutes, I worked that question out. I was so frustrated. Nevertheless, I know that I must look forward and do better works in order to make my mistake up.

Week 8: Assignment 2 and Big-Oh
-The tutorial goes on well as usual. Adam does a really good job as a successor of Yana. He explains things in an easy and efficient way.
-It takes me a while to understand the entire meaning of the Big-Oh expression. Besides, I still have a little doubt about the part "produce non-negative real numbers as output". What I wonder is, certain functions can produce negative numbers as output with natural numbers as input, such as n^2-3n or n^2+n-5, if we take n=1. I should really talk over this with Prof Heap or Adam sometimes.
-Assignment 2 is not difficult, but it definitely requires a whole bunch of carefulness to finish it flawlessly. Although I have checked it several times, I am still afraid about some mistaks in format (e.g. indentation) and in detailed proof.
