Sir, I am a regular student of class XII and donot want to appear in class XII exams 2015. I had also dropped in class XIth. Is is possible that I can appear for XII only theory of all subjects in 2016. Whether I have to submit medical certificate not to appear in exams or there is no need. I am non-medical student. Will my practical marks (Physics, Chemistry and Music) for which I have already appeared, carry farward for 2016. Please tell me urgently because papers are from 02.03.2015.
