Hello Aspirant,

See as we know that in JEE-Main there are two papers, one is for B.Tech/BE and other is for B.Arch/B.Plann. so if you clear the cut-off for JEE-Main Paper 2 then you will be eligible for further level which will be JEE-Advance, it doesn't matter whether you qualifies paper 1 or not until and unless you seek admission in B.Tech/BE course. But note that if you are seeking admission in B.Arch through NITs then you have to clear the JEE-Main with good rank too because admission to NITs are not decided by the cut-offs, admissions are taken on the basis of your rank.

I hope this information cleared your doubts.

Good Luck!!
