a. The topic that mostly impacted me is the topic about vectors. Since vectors can be used almost everywhere in the real life, then it can be applied to almost everything in life. From real world physics to language, vectors can be applied.

b. If I can summarize the subject into one word, then I can say that the word is enlightening. It enlightened me to the various applications of theories to real life. And I can say that it is quite stunning as well as exciting.

c. My parting message to this class is to never give up and have fun. CS 130 is a fun subject, so you can enjoy it as much as you want to. Just remember to not leave the learning part just because of the fun that you experience.
