When I was a kid I used to hate maths a lot but once my mother scolded me alot and that day i promised myself that whatever happens but anyhow I need to be best at this subject and i did that so, why can't you. And there was a time when my friends started to call me not by my name they used to call me Mathematician. Because according to them I was very good in that. So i'm here to help you with your problems. Since 9th standard I used to teach my younger siblings and there friends sometimes. I had helped many of my friends in completing there assignments and exam syllabus on time. I had scored 99marks in engineering mathematics. During this lockdown period I taught maths to my niece and nephew.
I am a very kind and polite person so because of that no one ever find any kind of difficulty when I teach them. During my engineering time I have learned my all subjects very clearly. I have qualified Gate exam in first attempt and my concepts are very clear for electronics engineering subjects due to which I used to score good marks in my B. Tech exams so I think this makes me a good teacher for those students who find difficulty in technical subjects. I am very good in calculations. During my college time I used to help many of my friends in solving the Gate questions. My main motive is to teach you well in a very effective way in a short period of time.
