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

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.

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.

I knew nothing about programming before this course. But in my exception, programming is a really cool stuff. It has the ability to make a code run which forms a completed application in the end. So far  I have learned the foundational using of DrRacket which can do mathematics quickly or do other things like changing the size of a picture with simple commands. It is interesting to predict the steps and final answers of a command. If my answer is the same as DrRacket says, I feel that I have less distance with programming. Actually this course is much easier than I expected. When I heard about computer science, I image that the course may ask me to make an app by myself as an assignment. Also it is easy to prepare for quizzes. It is not hard to comprehend a week's lecture thorough a review, especially the time I working on the weekly lab. I only need to follow the instructions and watch the result. After several tries, I think I am pretty confident about the stuff which will be qui

To be honest, my intention to choose CSC104 is not innocent. I heard that this course is easy to pass which attracts me a lot. However, after few weeks' study; I found this course is interesting. It is simple but I still need to practice and do the instructions in order to understand the result of the function. DrRacket is not hard to run but I wish I can learn more through it. I would like to know more about computer science rather than predicting the result. I wonder the future lecture which I can learn more skills on using DrRacket. Actually, I am really interested in programming. For example, making a simple app which I can use on my phone or a small package on my computer. I always have a lot of strange ideas and I am pretty sure that these ideas are bright. If I know how to program, probably I can create some useful app to help people.
