This week's material focused on to learn how to let DrRacket memorize the definitions that we ought to reference later on, by programing the definition of what we mean by certain values. This involved how to play with images with picturing-programs, mostly on defining a set of sequences which creates expected outcome (rosette program).
The material seemed intimidating and overwhelming at the beginning, but it turned out better as the lecture proceeded. Defining a set was understandable once the model is unfolded (as it is done on the videos online), and I found myself picking up faster than I expected.
My worry for now is that I'm not so sure yet with what the last video about definitions was dealing with. Since I've ran out of time by the end of tutorial, I wasn't able to finish watching this video. On top of that, I was still unable to finish copying what the third video was doing with rosette program. I noticed that the difference in my program with what is on the video was the different images, but I saw no other difference, and TA was struggling to find it as well (unfortunately, the time ran out before he fully explained the program). So, perhaps I should go over this part by next week.
And by the way, I didn't mistake my tutorial room this time. The quiz from last week turned out to be full mark, so I would like to keep up with the material as much as I could, starting from reviewing this week's material.
Hope next week would be more successful than this one.

You can raise your questions next Fri during lab. Btw, you can install DrRacket on your own computer, and work on the materials presented in videos from home when you have time.
