This week is midterm test which I also learn new stuffs from the review. Last week we learned about list,apply, map and range. The idea about range is a little bit confused because the end number is not included in the list. In addition, I cannot understand map at the first time because it looks complicated. However, when I think it as math, it turns out really easy. Also I know something about rotate from the past test. A positive number is ccw and if I want to rotate cw, it should be a negative number. About define and check-expect, most of my friends think they are hard but I am not. I just need to copy down some part and change it into the new function.
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...
