how good is 168 marks in jee main 2020?

At a score of 168 these will be the result stats.
Your Overall Percentile is: 99.2 - 99.4

Your General Rank is: 5336 - 6986

This is really a good percentile. At This percentile you can get admission in any of the old nit and gfti but you may not get your desired branch. But if you somewhat compromise with the college then you can also get branches like computer science and information technology. all these are for general candidate and if you are a other category student then this score will be proven more magical for you as you will get one of the topmost NIT in GFTIs that too with desired branch.
Hope it helps
