Hey Rashi,

Only students who have mathematics in their 12th grade can apply for entrance exam of DU JAT. You can have maths either as your core subject or an optional or additional subject.
Don't confuse if you are able to fill the entrance exam form without having any difficulty despite of not having maths as one of your subject. Previously people have applied for test and appeared in the same. When they are called for the interview non maths students are not called for the GDPI. At any cost any of your request will not be entertained at the time of GDPI.
So if you're a non-maths student you won't be able to get into the colleges of DU.
Hope this helps!
Good luck!
