Featured Review:

## Very knowledgeable tutor, and very well prepared!

Justin, 17 lessons with ChristopherHe was sure to understand and review any necessary files needed before starting our session so that he could be prepared. This is very appreciated. He is very patient and willing to slow down to explain any details for which you might need clarification. Christopher is very fast and efficient with his time. I will definitely continue working with him and I highly recommend him to anyone needing help with python coding concepts and data structures.

I have been tutoring students in math and computer science for over 10 years. I enjoy working on challenging math problems and teaching fundamental skills in a new way. I believe everyone can improve in math and computing, and I aim to develop a pathway for improvement with my students. I begin by working on a plan and goals with each student. Then I work on some easier topics to build confidence as we work towards the hard stuff. This also provides an opportunity to understand the student's...

Christopher has provided examples of their subject expertise by answering **9 questions** submitted by students on Wyzant’s Ask an Expert.

## Extremely knowledgeable and patien t

During the meeting we worked on a problem set that covered DFA and NFA. We looked at the class of regular languages that are defined by multiples of integers. We wrote DFA for 2 and 3 and proved that there was a DFA for 6.
