My part time job is a tutor. I have been teaching my younger brother from two years ago. subject is mathematics, it was but somewhat difficult at first. A unit of this day was a probability. this lesson usually cause pain to students. Therefore, I was anxious that he might give up with preparation. He has achieved it fortunately although there lay difficulty in the way. I was so happy. Teaching someone is very hard because must assume the responsibility. However gladness is doubled when students got a good result. I hope he’ll get a good result in a final examination.
