Hi Jappreet,
A person who doesn't have mathematics in class 12th isn't eligible for DU JAT as they have completely mentioned the eligibility criteria on their official website :Candidates belonging to the General Category should have an aggregate of minimum 60% in four papers including English, Mathematics and other two subjects from the list of elective subjects as approved by the University of Delhi. So, Mathematics and English are compulsory subjects for applying to DU JAT and someone not having maths in class 12th can't appear for this exam.

Hope this helps. All the best.
