Krishnandu Hazra Assistant Professor || Ph.D Scholar in CSE

Hi! I am Krishnandu Hazra, currently pursuing (final year) of Ph.D. in Computer Science & Engineering at the National Institute of Technology Durgapur (NITD), India. I have completed the B.Tech in Computer Science & Engineering in 2013 from Jalpaiguri Government Engineering College, West Bengal, India, and completed the M.Tech in Computer Science & Engineering in 2015 from Kalyani Government Engineering College, West Bengal, India. I have qualified GATE in Computer Science in 2013.

Currently, I have more than 7 years of teaching experience in various subjects of Computer science in colleges. I have more than 4 years of online teaching experience. I have experience in teaching students across all over the globe and most of my students are from the USA, Canada, Switzerland, London, UAE, Germany, Australia, Italy, Lebanon, Hungary, etc.

The main focus of my teaching is first to clear the basic and fundamental aspects of the subject then the exercise. I believe that if a student has clear knowledge about the basic foundation then he will be able to solve complicated problems automatically. However, sometimes basic knowledge is not enough to solve because of the complexity of the problem and there some trick is needed. After completing the basics, I provide some essential tips for the tricky problem. After teaching all the fundamentals, I take the test for making the evaluation. For the test, I provide some test papers. After taking the test, I clear all the doubts about the questions.

**** I give regular online classes.
**** I help with the assignment solution.
**** I help for preparing for the exam.

In the following, I have added the name of some leading universities across the globe from where my students belong.

1. ETH Zurich, Rämistrasse 101, 8092 Zürich, Switzerland
Subject Taught: Algorithm Design and Analysis

2. University of Toronto, 27 King's College Cir, Toronto, ON M5S, Canada

Discrete Mathematics

I got in touch with Krishnandu a week before my exam. He was extremely responsive. His command on the subject was excellent. His rate was very reasonable. I could flip to any question in the textbook, he always knew how to solve that question. Due to Krishnandu, I managed to score over 90%.
