David is smart, personable, and reliable. This was his second tutoring session with my daughter, a junior at a specialized NYC high school. They worked on quite a few problems relating to Euler's Identity and the transition between trigonometric functions and the complex numbers. This included evaluating complex numbers to complex powers, rewriting formulae, understanding complex numbers as a rotation around the plane, and interpreting the complex angles providing for values of trigonometric functions outside their normal parameterization. I just wish I could understand all that :-).
Nathan helped me work on my pronunciation and writing for more than two months. He is very helpful and patient. Studying with him like exploring in a journey. You will never know what you will learn in the next second. I enjoy the courses offered by him. He is also very professional. He always recommends good learning materials to me, which are very useful for my future study.
She has been a great help with Jayden in reading, math and writing. I would recommend her for tutoring in these subjects.
