An experienced educator with over 5 years of teaching experience, I have had the privilege of mentoring more than 100 students. My expertise spans foundational high school courses (9th–10th Science, 11th–12th Biology) as well as advanced engineering disciplines (B.Tech & M.Tech). I hold a B.Tech, M.Tech, and Ph.D. in Biotechnology, alongside a competitive GATE qualification. My approach focuses on building deep conceptual clarity and critical thinking, followed by structured problem-solving, regular assessments, and rigorous PYQ practice. This exam-focused strategy ensures students achieve outstanding performance in both board exams and competitive tests.

I started my teaching career in 2005 in that year itself I got a chance to take class in 10 for one month for leave vacancy. After that I got the chance in 2011 in another school, then it continued. Taking class in 10 it was a challenge because responsibilities are more. Both parents and students are in stress, at the same time the school management also. If the results are not satisfactory it will affect to the reputation of the school. So the teachers are alert always .All the students have to face the board. So the preparation of each and every child is important. For that conducting special classes ,morning classes. Conducting evaluations in proper interval. After every evaluation a session with parents in school is very important. Because they are more stressed than students. The year tenth is important because it is the turning point of each student . The effort of all the pupils will be fruitful when we get the good result. Teachers especially those who are taking in class 10 they are not bothered about the salary which the management as paying to them, of course it is a pain to their personal life. Once if we are standing in front of the students our main attention was that whether the concept will be reaching to the pupil in the right meaning and sense. In that time we are not bothered about the payment. If the student got the concept and scored good in exam that was the great reward for teacher. After the schooling that student and parents never forget that teacher in their life every important movements they expect that teachers presence there.
