It is quite difficult to say which board is much better for NDA as both of the boards are prestigious boards. However the major difference between Central Board of Secondary Education Board and Indian certificate of Secondary Education is that the first one focuses on concepts which are theoretical where is the second one board focuses on the practical knowledge which a student earns. If we talk about the level of the syllabus of these both boards then Indian certificate of 2nd Education Board has more complex syllabus in comparison to Central Board of Secondary Education. Most of the students in India take Central Board of Secondary Education because it helps students to prepare for different national competitive examinations.
