I have got 71.0345 in jee MAn exam , Iam belongs to PC category whether iam eligible for join engineeringcoursein governmentorprivate colege

Hello,
Give us exact category information (there's no PC category!)
For general category student, your chances are too low of getting admission in government colleges, you can expect only private engineering colleges like CV RAMAN, NIST, GL BAJAJ, etc.
Good luck.

Hello.

It depends on your rank rather than your score if you can get into an NIT. The official rank will be released by NTA after the conclusion of the April session of the exam. Your rank is bound to vary as the best of the two scores will be considered for the rank list. You could predict your rank using this formula:

JEE Main 2019 rank (probable) = (100- NTA percentile score ) X 874469 /100

You could then refer the previous year cutoffs to know your chances of getting into a college:
