With JEE Main rank 101,571, getting ECE in DAIICT is very hard because their cutoff is much lower, around 12,000. Even with reservations, your rank is higher than their usual cutoff.

You can try other private colleges or state counseling where cutoff ranks are higher. Also, some colleges have management quota but fees are more.

Focus on colleges where your rank fits the cutoff. If you want, I can help find good colleges for your rank.
