I usually start with the basics then intermediate problems upon completion I will start with the fundamentals, I often use power point presentations for better understanding of the math subject with examples that everyone can understand with out having any problem, I like to have feedback after each session before moving to the next session or subject, I would like to have a brief test after ending a subject to understand my students as we as to come up with new ideas. Tutoring is not just finishing the course I believe. I see mathematicians is a great tool to excel in life rather than a subject, if you good at math you are good good at all I believe.
