Ya sure good teacher

Yes I recommend A.N Sir because I learned from him for 3 Years. He is very talented lecturer. He have many knowledge about Biology and biotechnology. His technic of teaching is very good because he specify any topic with many examples by which we can easily understand that topic.
I strongly recommend Abaidya Nath Singh Sir and I want to watch him as a Teacher.
