Hi Harsh  !

I think your code number will be '02' in this case provided the fact that you had english as one of the subjects in your board exams in 12th and in place of maths you had any other elective subject available at your school and gave the board exam for the same and Also you have not appeared for the board exam from any open school or as a private candidate.

Hope this helped. Please do contact us if you need any more help with filling out your application form. all the best ! :)
