Dear Candidate ,
With your given rank , your chances of getting CSE in top NITs or IIITs are slim , but you do have a good chance of ECE , Mechanical , or Civil engineering in mid-tier NITs - especially if you have a home -state quota . At IIITs , CSE might be difficult , but ECE or IT branches at newer or tier -2 IIITs ( IIIT Nagpur , Agartala , Manipur ) are possible . In GFTIs , getting CSE or ECE is more realistic , with institutes like BIT Mesra being good options .
Participating in JoSAA counselling and carefully listing choices based on closing ranks and quota benefits will improve your chances .

Dear Bhindi,

at 600k rank getting in top or mid tier government colleges are tough but you can get good private colleges like KIITS, VITS, Amity etc most have direct admission without consider so JEE ranks. if , you go state government exams, be open to other branches, you can consider drop one year.... I mean doors open

Get your best

Thanks

Best of Luck
