The final exam week is coming and I found that this course, CSC104, is a wonderful fundamental course for beginners in computer science. The most important thing for us to do is to manipulate DrRacket well. The functions I learned so far are not as difficult as I think before take this course. It is significant to identity various function types. For example, the way writing a base function is important for the later recursion functions. Since I learn about simple type of functions, it is getting complex. However, as long as I keep up with the practice each week, it is easy to get full marks on each week's quiz. In addition, it is helpful to do the past exams. It is a good way to review and learn new samples that do not appear on the quiz.
