Online Classes I am a passion driven tutor, with a rich experience of teaching students of intermediate level, Physics, Chemistry and Mathematics, in a real classroom environment at my residence, for nearly 6 years. I have taught about 10 to 16 students every year, during this period I used to enliven the students through practical examples from my field of service, to develop their fundamental concepts/interest and enthuse them to gain a deeper insight into the subject.
