Hii

First of all, congratulations on his success. He has done a great job. Although the official announcement regarding the cutoffs is yet to be made and so we can not guarantee as of now about the admissions because it will be made on the basis of the qualifying cutoffs only. And the cutoffs would be released after the declaration of final result in april. 
But as per previous year cutoff trends,  he stands a high chance of getting admission into NITs. or any other good colleges.
But for IITs, please be informed that admissions are based on the scores of JEE Advance. For that you need to be among the top 224000 students in MAINS.
Hope this helps

Thanks!!
