Rather than going for Anna University, I would highly recommend you to go for well reputed national institutes like Indian Institute of Information Technology Una and IIIT Bhagalpur. A brief comparison of both are as follows:

Ranking: Both are new colleges and thus unranked, but Una is a better and more beautiful place than Bhagalpur.

Placements (ECE):
IIIT Una: Highest: 44 LPA, Average: 11.01LPA
IIIT Bhagalpur: 30 LPA (CSE), Average: 8.5 LPA (all)

So, in general, IIIT Una is a much better bet in all aspects. Hope I have answered your question. All the best!
