Stuffs we learned this week through the lecture was quite similar to the last week. We still focused on defining functions and identifying booleans; however, I found that it was getting easier for me. Now I can answer whether the boolean is true or false quickly. Actually I also several good ways to memorize like if there is "and" and "false", then it must be #false. What I learned new this week was the way to hide steps. If an intimidate step was calculated before, I can use hide to hide the calculation which makes the step clearer that I do not need to do it again. With the hide command, it turns out to be easier to do complex functions since I have already calculated the answer for an intimidate step before.
Now the materials are getting complicated which means I need spend more time on reviewing lectures and preparing for the quizzes. Usually I prepare for the quizzes by doing assigned questions on DrRacket; however, I found that I would forget some steps several days later. So I decide to do these questions twice a week which can refresh my knowledge and examine how much I remember. Around last week during the exam week, I did a past exam about making a "Yingyang" image that made me really proud of myself. It took a lot of confusing steps and it is a detailed image. After the result showed, I felt proud that I could create such an image. These days we learned about condition which initially I thought was hard. Then I find similar questions from the past exam and practice which help me get familiar to condition. I still seldom ask questions in tutorial but I think it is okay because the material is not difficult. Also I will discuss questions with my friends when I have question...
