Hello Preety Jha,

Well, I am assuming 6510 rank to be your AIR and under female-only seats you have except CSE and Electronics, all the branches of B.tech 4 years courses unlocked and you have a good chance on them. And in 5 years integrated course, except CSE and maths and computing branch, all branch are unlocked too! And There is a 3% increment in female-only seats so, yes you have chances of ECE 4 years b.tech too!

Hope This Helps,

All the best, and feel free to ask any further query...
