Hi Mohit.

With a percentile of 71.64 in JEE Mains in SC category( I hope that in the question, you meant percentile and not percentage), you can expect your rank to be nearly 442417. I used this college predictor to predict this answer, https://engineering.careers360.com/jee-main-college-predictor?icn=QnA&ici=qna_answer .With this percentile, you may get admissions to these Govt colleges:

1. United Institute of Technology
2. Madhav Institute of Technology and Science
3. Samrat Ashok Technological Institute
