Hello,

IIT Jam Examination occur for admission IITs, NITs and IISC colleges. There are some particular subjects like mathematics, physics, geology, chemistry, statistics, biotechnology etc. So every department have different cut-off marks for admission. Infact every IITs and NITs college cutoff for each subjects also different.

You didn't mention any subject name fot admission. And not mentioned your category. So i assume that you are a general category student. For general category student 6143 rank is very high for this colleges. If your rank between 2000 then may you have some chances for getting IIT college any one. And above 2000 may be you will get NITs or IISC colleges.  But in this rank you can't get any college above this. You can try for another government college for admission. You will get good government college surely.

All the best.
