Can I get iiit allahabad only from doing jee pyqs

I'm preparing for JEE Mains and aiming for IIIT Allahabad, especially for CSE/IT. I’ve been focusing mainly on solving previous year questions (PYQs) instead of following standard books or coaching material.

Is it possible to secure a rank high enough for IIIT Allahabad by relying only on PYQs? Or do I need to supplement my preparation with other resources? Would love to hear from those who have cracked it or have insights!
