CBSE schools refer NCERT books which are universal in the entire country. So, a student who follows NCERT books will not have problem if he or she shift to another state because the syllabus is same anywhere. This is not the case for other boards.

The books preferred by these boards are easy for some while tough for others. Some have good teachers, lenient examination while some do not have these facilities. It is important how one has progressed in life in spite all of these.
