Testimony

Here is the reference statement I have prepared.

I have observed Ian tutor an 11 year old boy in Math. He is patient, encouraging and understanding towards the student. Though the subject matter proves to be difficult for the student, the student is encouraged without feeling hurried or frustrated.
