CSC165 SLOG week 10

For the definition of big O and big Omega, I didn’t understand when it first introduced, but in the tutorial, the TA explained again and it got much clear. It was just the quiz from last week was a little bit hard and I did bad on it. So, the tutorial is pretty helpful for me. A big part of this week’s lecture is about the proof of big O and big Omega, they are understandable, but in Friday’s lecture, I felt like I spent all my time copying notes and there was no time left for me to think and learn. However, this always happens to me, I want to listen to the lecture but I worry that I will forget everything after without notes or sometimes I don’t even understand the lecture. Maybe I should change the way I listen to lecture but I don’t know how. For now, sometimes I review the notes from lecture if I have time.

On the other hand, the term test result came out; I did worse than I expected and I will take my test next week since I don’t know why I lost points in the first question and I want to see how I did in the other question so that I can figure out the questions that I didn’t get them right. I sometimes do worse in test than I expect maybe because my speed is relatively slow and I always run out of time in test, but I can’t find a good way to improve my speed. Though I guess that doing more practice probably helps, I can hardly ever achieve.


The notation in lecture said that assignment 3 will be posted during the weekend, so I plan to start it early since the questions in assignment will be hard and it will probably take lots of time to finish it. Hopefully, I can do some parts of it in the long weekend but I still have my csc108 assignment. 

A student's slog reminds me that when picking variables in proofs such as big-oh, we need to be careful of the restriction, since it may cause the whole proof to be wrong.

  1. I also feel that the time given for tests is quite short. Since not much practice problems are given by the prof, I usually try to redo all the examples from the class notes. Maybe you should do the same.

  2. Maybe you can do some previews before classes. I had the same problem following the lectures while taking notes on my laptop for the first two weeks of classes, it really frustrated me. Then, I started to preview every Sunday evening by going through the lecture slides for next week. It gave me a general idea of what to be taught, and this method turned out helpful. Also, you may refer to course notes. Hope these will help ^_^
