I have pursued BTech in civil engineering from College of Engineering Trivandrum and obtained CGPA 7.78 out of 10. I had secured AIR 2543 in GATE2020 which qualifies me to pursue masters from the prestigious colleges of India.
Along with my bachelors I had tutored students upto class 12 subjects like physics, chemistry and maths. I had also taught underprivileged children while volunteering for a NGO. I believe these experiences of mine will facilitate students to comprehend my teachings. I am also versed with the online platform through my tutoring experience at Course Hero. I am sure my hardworking nature and quest for knowledge will be an asset for the overall academic development of the students.
