I want to thank Kiran sir for all his efforts. He has the habit of making difficult topics easy to understand. I always enjoyed to learn through Sir’s lectures. I was preparing along with job and all these concepts helped me in job as well. Sir’s way of explaining topics is extremely good. He states the problem in such a way that I used to approach the solution before he actually solve it. He explained every topic in depth and that helped me in cracking GATE.
