i belong from obc and i got 35 percentile in jee main paper 2

If you are from Obc. Then there are chances that you might get some good colleges,you have to apply for the Nata counselling program, then wait for the results.

but sir i m not qualified in nata but i attempt  jee main paper 2 so i m confused that only score card is important or qualification is important for admission in b.arch through nata

See.. Akanksha  As per as the NATA admission concern,you need to score good marks,for getting a good college,which may have all the interested courses.Both the exams are conducted by different Organisations so far.If u aren't selected in Nata But u get selected in JEE PAPER 2, then you might not give you a good college .Because you know that you need to have a good score,that's a must. And about qualifications.people just need to know that you scored above 50% in 12th and The main concern is you score Well in your Competition exam.
