First binary number is the most highlighted of all the topics because it was very hard to understand, it takes me 1 whole month to understand it. But when I understand it it was very easy and interesting. Second, the using of compass to draw many things, it is very interesting by just looking but in reality it is hard but also fun, it is like we were an engineer using compass. Thirdly, the roman numerals, at first I thought it was very easy but in reality it is really hard making the score I made in the first quiz of the year only 60%, it made me depressed very much. Although the year was hard, but I really enjoy your teaching Mr. Gary. I wish you will teach us in the next year.
