Career Experience

Now am in retirement after decades of teaching in boarding and day schools where tutoring is a regular part of a day of helping students learn the concepts and find success.

I Love Tutoring Because

I have a real appreciation for the opportunity to make a one to one contribution to achievement and to understanding science and the beauty of how life, our world, and the universe works. Tutoring gives me the reward of daily contact with students.

I worked well with my tutor, but the only thing I suggest is to clarify more of the formula. I know my teacher was unable to explain things clearly so I wished that I was able to receive a better explanation of what I was working on. Otherwise, I felt like I was able to grasp the majority of the concept.

Si understand the value of the audio service in explaining the content i needed to cover. He took the constraints of my instruction needs and just worked through the problems with me.
