We finished course material about proof and started sorting algorithms this week. We learned about inferences related to proof and learned insertion sort and selection sort, which are two basics sorting algorithms. I did not catch up what is being taught at the end of proof. I learned about sorting algorithm in my grade 12 computer science class. I hope this can help me understand the material we are going to learn in the future.
This week's tutorial is the key for me to understand the course material of proof. Before the tutorial, I did not know what to start to prove a statement. Instead, I only know how to write the structure of a proof. During this week's tutorial, the TA made us work on the problem for an hour and ten minutes on the 3 problem set questions. Since there are so much time, I at least tried to start doing some proof. After the TA taking up the questions, I think I was more confident about proof. I think I did the quiz right because it is really similar to the question I just did.
Assignment 2 is going to due very soon, I found two teammates this week. Hope I can do well in assignment because it weighs a lot.

We continued learning about proof in this week's class. Danny helped us solve some sample questions. In Friday's lecture, we learned about proof that needs to discuss in different case.
I found that I need to concentrate every minute in this class. In Friday's lecture, I was unable to catch up what is being taught after just picking up my eraser from the ground. Maybe it is just that I missed the key point coincidentally. It is really hard to distinguish what is course material and what is irrelevant from Danny's lecture because some of his joke is weird and his voice is not that clear. So, the best way is to learn is to try to concentrate on the lecture. In addition, I still find that some of his writing is not recognizable. For example, in Friday's lecture, when proving n^2+n is even number, Danny writes something like "N closed under +, *", and then the problem is solved. It doesn't make any sense to me. I probably need to go to his office hour to ask him about it.
The mark of our first test came out this week. I got 2 marks wrong for the first question, which is my most confident part of the test. I could not make it for this week's Danny's office hour so that I did not get the test. I am going to get the test next week and look at it carefully to see what my question is. I am satisfied with the test since I was not confident at all for this class and treated it as the hardest class this semester before the test, but I also feel bad about not getting full mark. The first question is the easiest and I should do it right completely. Just be careful in the next test and listen carefully during the lecture.

What I learned this week is the structure of the proof. I learned about we need to make domain assumption and the antecedent assumption. Teacher assistant gave us some examples of more complex problems. The material covered this week is not much related to the material before so that it is like a fresh start. What is being taught this week is relatively easier to understand.
The biggest challenge of this week is the mid-term test. Fortunately, professor allows us to use an aid-sheet. I really like the idea of aid-sheet because it can help you go through the knowledge while taking notes of them and you can use is to help you during the test. After finishing the aid-sheet, the review is almost done. Since I am not confident about this course, I looked over both Danny and Larry's slides and the course notes. It takes a lot of time, but it is worth it. I also looked over all the problem sets, assignment 1, and the past tests. I basically looked at any course material that I am able to find. I am actually confident before the test.
The first problem in the test is really similar to the past test's first problem and it is easy to do. I am confident about getting the problems correctly. I can do the other two problems in the test, but I am not sure if I did them correctly. In terms of the second question, my answers of the negations and determining which statement is true are correct in terms of the solution Danny provided today during the lecture. I am not sure if I can get full mark with my explanation. I provided a counter-example for the wrong statement. I am sure my direction of the third question of the test is the same as the correct answer. However, I also have a different way of explaining the reason.
I tried my best for the test and I hope it goes well.

I found this week's course material challenging for me. During the lecture, it is hard for me to absorb what is being taught by professor Danny. The explanation on the slide is not clear enough for me to understand. Besides, I sometimes cannot hear what Danny is saying clearly. I always feel that the professor skips something that I cannot connect what I already know to what is being taught. I think the professor should give us some more easy examples to help us understand the concept. I am still unable to get used to the way how Danny teaches. I cannot follow where he is leading us. Sometimes, I don't even know which part I don't understand when I cannot catch up the lecture. It is really difficult for me to learn from lectures.
Fortunately, I found some help this week. I thought about looking for extra help provided by teacher assistant, but I feel like I may need them to teach me about the course from the beginning. Instead, I looked at another professor Larry's course note. There are some easy examples on the slides, and the explanation is more clear and easier to understand. I spent the whole evening on Monday going through professor Larry's note and I am confident about first three weeks' material.
Regarding to the assignment, I typed the answer to the computer on Sunday and sent it to my teammate. Then, my teammate made some changes. I am confident about the assignment because my teammate has said that she enjoys this course the most.
I am satisfied about this week's tutorial. Because of the studying on Monday, I understand how to negate and how to transform between implication, disjunction and conjunction. I can do the problem set by myself and I can understand what teacher assistant is teaching. I am sure I did the quiz correctly.
Mid-term test is on next Wednesday. I am anxious about it to be honest because the lecture is too hard and unclear for me to understand that I fear I have already missed something for sure. I should look over both professor Danny and professor Larry's notes and do the tutorial problem set one more time. Just try to find which part I do not understand and find some help to solve it.
