It's quite a great time spend in Houghton as a tutor. As a university-paid graduate student, the working time is very flexible. Basically when there's a office hour or grading job, or tutoring hour, student may come in and asking questions about subjects learned in the class. I payment is just enough for paying the tuition and surviving here. I like the job, because I'd teaching, the way I enjoy it is to spend a joyful time with students and get the concepts reviewed, at that moment I'm not just a tutor, I'm also a student who's eager to learn those almost forgotten knowledge.
