Technical knowledge is essential today grab it from a engineer today .

He has been teaching sincea year and have been very confident about his teaching he always starts from the very basic and then goes to advance. He has been a great mentor now

I am highly recommending this teacher because he understands each student's motivation. He is capable of demonstrating each topic due to life experiences. He is trustworthy,creative and educated.

I have known Mr Roop Kumar Chatterjee for a year now, and I think it's safe to say that he is the smartest person I've ever encountered. It doesn't matter what subject we are discussing or learning, he has some good skills to have knowledge about the topic and showing a passion for knowledge that is simply unparalleled.

He has an uncanny ability to make anyone else understand any subject. He is a naturally gifted teacher and leader.
