Teacher is an important part of anybody's education.

I completed my post graduation in 2005. During my school and College, I always had difficulty coping up with things in classroom. But my Telugu teacher Mr. Hussain Budde during my 7th class , I used to enjoy his way of teaching, way he used to engage students by teaching lessons as stories. After that, I never found any teacher who kept sessions so much engaging. I don't want to blame my teachers, I always felt they could make sessions more engaging. I always had to spend time outside class hours to cope up with every minute of classroom session.

I as a teacher, I adopt a style of teaching which keeps session engaging and ensures that students give 100% focus on the session. I always wanted to be that one teacher, whom my students will remember for lifetime. I am making sure that, rest of trainer's also follow same.

I want your 6 months of education at VLSIGuru to be among your best learning experiences. We at VLSIGuru will do our best to make this a memorable time.
