Hi,
I am a tutor in Mathematics subject. I love learning and teaching too. I understand that each student is unique and hence I need to change myself - while communicating with each one of the students - so as to make the activity of learning a play thing, once and then for ever!
I believe in activity-based learning, with the help of tools/games/students participating in events- especially outdoor ones. I also believe in continuous learning and teaching to keep myself up to date!
Cheers!!
