His extensive understanding of the subject allowed him to clearly show my son how to work problems and understand **Pre**-**Calculus** concepts. He promptly provides reviews of each session via email, which let me know how my son was progressing. Joseph was definitely a great success with my son. I highly recommend him due to his organized planning and thorough knowledge of mathematics.

The "tutorials" that were given to me as lessons to learn those **pre** **calculus** topics were an enigma to me in the way they explained it and I was left with more questions than answers. Then I decided to get tutoring help from Kate and helped me a great deal! She was kind, patient and was willing to help me with problems I was confused on. She's a great teacher and 100% would recommend her to anyone who is struggling with **pre**-**calculus**.

Nader continued to tutor my son on a weekly basis throughout the remainder of the school year. He is very knowledgeable in the subject matter, patient, and very dependable. I don’t know how my son could have gotten through **Pre**-**calculus** without Nader’s assistance, and more importantly, I feel confident that my son is now prepared to tackle Calculus at the college level next year. I would recommend Nader to anyone needing a math tutor.
