Hi Amit, hope you are doing well, yes with 72100 you can try for Dhirubhai Ambani or Nirma college. But you need to pay a donation in both the colleges of dhirubhai ambani and nirma college to get admission into the respective colleges. You can even try for some private institutes which are as good as indian institutes with your rank. I suggest you once go for rank predictor in jee mains in careers to know more about your admissions through jee mains.
