Hello Dhruv,

To approximately predict your jee main paper 2 rank you also require your nata score. With the help of your nata score and jee main paper 2 the ranks are alloted. Along with the jee main percentage the score you obtained in nata will also be considered in the allocation of ranks. For the more clear details you can refer this link, https://engineering.career-s360.com/articles/jee-main-cutoff-for-b-arch-b-planning.

Hope this helps.
