I was always inclined towards tutoring since my freshman year in college. I started with guiding my younger cousin in pre-calculus and it boosted my self-confidence when he scored a perfect 10 GPA in his school. Later, I went on to join and dedicate two years of time to an NGO named "SAHYOG", which aims at teaching children who come from financially challenged families and cannot afford basic education.
I, along with a team of 3 others, conducted classes of C-Language for juniors in my 4th semester of graduation because of my clarity in C-Programming and ease to interact with students due to my past experiences. I also volunteered for a short period of time for the National Service Scheme (NSS) for underprivileged students and received amazing feedback.
