CBSE 12th

I am sorry to say but your marks are not enough to get admission for B.Arch in IPU because IPU colleges consider above 90 marks in NATA for B.Arch.

Hello Amardeep,
Your cousin seemed to have obtained reasonable marks in 12th. Admission process in DU is online merit based or entrance exam based depending on course sought.

Hello Seema,
I can understand your anxiousness on failure of your cousin in 12th. But can you analyse reasons? Was it lethargy? Was it his disinterest in studies? These and other different factors need to be analysed. But you have to coax him into preparing, appearing and passing of 12th.

You secured good marks in class 12th, but with such low marks in JEE Mains, you can't get NIT.
So, apply for UPES, or if you have given COMEDK, then through management quota apply for Bangalore colleges or else apply for Amity University, Noida.

You can't do it this way.
You have to repeat class 11th and class 12th again with science.
If you can do it, then go for it.
If you decide to do it, please be firm and be prepared for opposition.
