Myself Tanmoy Jana.I am graduated in Mathematics from Midnapore College affiliated to Vidyasagar University, India.In my college days I attended so many seminers showed my presentation and gave lecture on my subject topics. And that made a good impression on all and was a great success. My best memories in my college days is about my friend circle . We used to study in a group and try to solve others problems. It helped us to remember the long and hard theories. Beside this I used to teach high school students in my college days . At first it was difficult for me. But with time I became able to cooperate with my students and able to understand their problems.
