We believe crash courses play very important role in revision of the syllabus and helps students to finalize their preparations of final examination. Further, our crash course also consists of a Test Series with 3 Tests during the Crash Course with the Final Test being full syllabus test based on JEE Mains/NEET pattern. We have designed a separate Crash Crouse for our old students who have already been attending our Weekend Classroom Program, understanding their special requirements. In this course we will emphasize more on those chapters which were not a part of our Weekend Classroom Course syllabus. Further they will have to face somewhat tougher papers in the Test Series. The classes in the Crash Course will be taken by our specialist teachers in each subject.
