Hello Aspirant,

If you clear JEE-Main Paper-1 that is for admission BE/B.Tech. courses then you can go for admission to NITs/IIITs/CFTIs/GFTIs for admission to BE/B.Tech courses and also if you qualify the JEE-Main 2021 cut-off percentile then you can appear for JEE-Advance which can take you to IITs as well. Same with JEE-Main Paper 2, if you clear paper 2 with good score then you can get admission in B.Arch./B.Plann. courses. Now if you appear for both and clear any one of them then you will only be eligible for the single course. Suppose you appeared for both the papers but can clear only Paper 1 that is for BE/B.Tech so you will be eligible for admission to only BE/B.Tech courses not for B.Arch./B.Plann.
