I have found no definition or clarification about “tutorial classes” in the mentioned G.O.No.(s) previously.
……”tutorial classes and home task”- had been mentioned by the G.O.
Tutorial classes are some special classes arranged in the schools for some specific purposes to serve the interest of the students i.e. to strengthen their skill/knowledge in any class subject they require. For example: If they are weak and poor performer in Maths, tutorial classes cane be arranged for Maths. Not necessary that it should be always related to their preparation for Madhyamik/ H.S. exams.
