What advice would you give a customer looking to hire a provider in your area of work?
Make sure you check references and look for someone with teaching experience. A math whiz does not necessarily make a good teacher; you have to be able to break a lesson down and tailor your planning to suit the student. The student has to feel s/he understands the tutor's explanations.
