CBSE 12th

The candidate has to give details of all the subjects considered by the respective Board of Education for calculation of aggregate percentage. In case of CGPA/ grading system, the candidate has to upload the formula for conversion of CGPA/ Grade into aggregate percentage i.a.w. the conversion formula used by the respective board at Stage-II. Few boards consider all the subjects taken by the candidate for calculation of aggregate percentage. In that case you will write all the subjects and the marks/grades/CGPA obtained in order to calculate the aggregate percentage. Few boards consider only the top few subjects among all the subjects taken by the candidate for calculation of aggregate percentage. E.g. Maharashtra board may consider only top 5 subjects for calculation of aggregate percentage, even if candidate has taken 7 subjects in class 12th. In this case the candidate will write the details of only the 5 subjects in the online application considered by the Board for calculation of aggregate percentage.

• Navik (GD) candidates always have to submit details of Physics and Mathematics as subjects in class 12th for calculation of aggregate percentage.
