I believe in creating a strong base of fundamentals in Students’ minds and helping them to weave various concepts involved in a topic which gives them different approaches for a particular problem and understand intricacies.
As a tutor, I always use a methodology that keeps the students intrigued which makes learning easier. I like to guide my students through the field applications of the key principles involved in a subject which further helps them to pursue a career of their choice. With persistent practice and efforts my students performed beyond their own expectations that became my constant source of inspiration and helped me improve my teaching skills on a regular basis.
