A teacher doesn't have to be smart. The teacher should have the assiduity to be brighter than the student.

I like the he teach. He catches the doubts of the student very fast and clear the doubt very fast

I like the way he use to teach....He use to catch the main mistake where the student stuck... I like the way he teach.

I like the way of teaching. He is very friendly with the students and tries to clear the doubts in friendly manner.
