I have been teaching since I started my graduation 3 years ago. As a student, working as Teacher/PA has been tough but made me learn the needs for student and how to help them resolve their problems efficiently. I feel good to be able to help out students because I'm passionate about teaching. My motto for teaching is to convey the knowledge I have to students in a way that makes them understand it without breaking a sweat.
