Chate coaching class was heard when I was collegeing and I believe its a good class for weak students. It was really helping for weaker student who were doubtful of passing for 10th and 12th board exams. This class was giving coaching on all subjects and important notes for only the question coming on papers. They use to make it easier for studing all difficult and lengthy answers especially for weaker students. Students prefer to join chate classes for studying and for guarantee of passing for the board exam.
