Comprehensive Coaching class cum test A very unique feature of DOB BOSCO College is CCC or Comprehensive Coaching class cum test. Once the portion is over the whole syllabus is divided into many sub units and days are allotted. Almost every day for four to five months children have a written test and marks are comminuted to the parents through SMS. Children wait for CCC to begin to prepare intensively. Time is given to study in the campus with the presences of their subject lectures.
