I got 83,729(gen) rank and 23,109 (obc) rank. Suggest best colleges sir in this rank.

Hi Vibhanshu, As per your rank and category, you can apply in NITs compromising with branch of course. You can try for NIT Rourkela and NIT Warangal for some integrated courses in M.S. If you want a good branch like CSE or IT , you can try for Thapar university or Amity University.

Although you can give exams of some reputed private institutes like BITSAT, VIT, SRM, etc.

Hi vibhanshu ,
If you can manage your four year with any branch and as you havent mention here for any particular branch let me consider that you have no preference for branches considering home state quota you can option for nit uttrakhand ,nit surat for integrated course of maths , chemistry or physics .

Nit roulkela all integrated 5 year courses,nit jalandhar almost all branches except computer science and other core subjects if considering GFTIs then assam university you can option for but if you are specific with some branch then with your rank ots hard for you to get into sought colleges of india.
Either you can prefer for topmost private colleges
Like srm or lpu university .
Hope it helps !!!
