About me

I like to listen music. It give me a lot of relaxation after taking long classes. It's good for mental piece. Beside this for physical fitness I like to dot he cycling.

I can Teach:

Matter , Chemical Substances, Periodic Table, States of Matter, Nuclear Chemistry, Electrochemistry , Organic Chemistry, Thermodynamics , Chemical Kinetics , Basics of Matter

Teaching Experience

I have been teaching college level and School students for last 15 year. I worked with number of organization and educational institutes. This journey of teaching gave me lot of experience. And at this stage I am able to develop my own teaching methodology which vary from student to student by knowing the interest and potential of student. I love to teach organic chemistry. reactions and their mechanism make wonder how the reaction take place. Physical chemistry is so interesting for me and I make it more simple to student by basic calculation. Inorganic chemistry is on finger tips with basic fundamental.
