If i get ranking between 21000 to 24000 which college is the best in terms of placement

In the rank between 21k to 24 k you will get top nits with branch like chemical , metallurgy, Information technology,production engineering,etc you have to compromise with these branch.To get branch like mechanical,electrical ,civil , Electronics and communication engineering etc.you have to go with average nits whose placement scenario is average.
To get better NITs you have to compromise with branch to get better placement.
You can ask if you have any other doubts.
GOOD LUCK!
