I love tutoring. I love doing it. I find it intrinsically satisfying to see the light come on in a student's eyes.
My first math lesson that I taught was when I was 5. My neighbor, still in diapers, kept skipping 4 when counting from 1 to 10. I worked with him until he could get all 10 numbers in a row, and match them up with his fingers.
My students drastically improve under my tutelage, generally seeing a two grade level improvement (F to C, C to A, for example), and all of them get a much clearer understanding!
I am committed to helping my students get the top grades no matter the cost. I will take extra hours with you, repeat myself a thousand times if I have to and guide you to the best of my ability until you understand the concept that I'm teaching you.
