I am graduated from amity university in 2019. my branch was mechanical and automation. in my graduation, i ranked 2nd in whole academics. I have 3.5 years of teaching experience. during final year of my graduation my major project is related with designing and simulation. as a tutor, my major interest is in classical physics. when i was in my graduation, i would like to teach my colleagues and juniors about the basics of classical physics. at that time only when i realized that this is the thing in which i want to excel. my friends any family supported me in this journey. i like to learn about the kinematics and dynamics of moving particles and it also fascinated me since i was in my secondary school. my friends and students also appreciated my teaching skills. they always gave positive feedback about my teaching skills that motivated me on this path.
