I FEEL IT IS one of the greatest fraud institute worst teacher. Not at all helpful please guys head to some other class rather going over here. They provide me assurance for placement in mnc or local company foget placements the faculty itself don’t know about Telecom .teacher don’t even bother they never co operated with me.in my s difficulties and concerns .they use to hurry a lot for completing the syllabusthey are totally fake.NOT RECOMMEND .
