Hi dear,
If you still clear JEE main paper 2 with good scores and rank you will not be able to get admission in IIT's. JEE mains paper 2 is basically for admissions into B.Arch., B.Arch in Town & regional Planning and B.Plan. IIT's do not offer such courses.
If you clear JEE Mains paper 2 with good rank, these are the Colleges where you can get admission into :

• School of Planning and Architecture, Delhi
• School of Planning and Architecture, Vijaywada
• Malaviya National Institute of Technology, Jaipur
• Maulana Azad National Institute of Technology Bhopal
• National Institute of Technology, Calicut
• National Institute of Technology Hamirpur
• National Institute of Technology, Patna
• National Institute of Technology, Rourkela
• National Institute of Technology, Tiruchirappalli
• Visvesvaraya National Institute of Technology, Nagpur
• School of Planning and Architecture, Bhopal

For admissions in these colleges you need less than AIR 3000 rank.

• All the best
