Not reliable. The telephone operator enrollment teacher in the College of Continuing Education will never tell you how to do it, but will only brainwash you to believe that this is true and really let people with less than 300 points in the college entrance examination get one or two books. Nothing for nothing. If you don't work hard to get into a good university, the tuition will cost1.5w. You don't know how much miscellaneous studies cost, so it's not reliable.
