Dear student,

Well supplementary examination is held for the students who unfortunately did not qualify 12th or likely get failed to get minimum passing marks in a particular subject.

Supplementary exam is held so that students get chances to qualify the exam.

However you should note that the examination paper of any particular subject in supplementary exam is not same as the board question paper.

The exam is held for testing the knowledge of students, hence the questions are asked on the same concept and from the same syllabus which is asked in board exam.

But the exam question paper is totally different with the previous one.

I hope this will helpful to you!
