I am a student who passed 12th cbse in the session 2013-2014, but I didn't have Mathematics as a subject, but as without it I cannot be eligible for JEE, I am planning to give mathematics as an additional subject in the year 2016, will I be eligible for taking JEE exam then? If yes, then what should I fill in the column of 12th passing year? Please inform in detail

Thank you!
