After my tenth and plus two, I have done my graduation and post graduation in the same subject chemistry under the organisation Calicut university. I prefer chemistry as my core subject because chemistry colours our world and it is everywhere in the world around us. It is in the food we eat, clothes we wear, water we drink, medicines and cleaners we use. I am interested in chemistry lab and experiments. One of my teacher in the degree class inspired me to become a teacher. His punctuality, way of teaching, way of communication etc affected me a lot. So I took Bed and selected teaching as my profession. Bachelor of Education modifies me a professional teacher. I am proud to be a teacher.
