John Rey - Know your tutor
I’m John Rey Castaños, a dedicated and passionate Mathematics tutor with over eight years of teaching experience working with Elementary, High School, and College students. I hold a Master’s degree in Mathematics, and through the years I have helped students not only improve their grades, but also develop confidence and appreciation for the subject. I understand that many learners find Math intimidating, which is why my goal is to make every lesson clear, engaging, and stress‑free. My teaching style is student‑centered and results‑driven. I believe that no two students learn the same way, so I carefully assess each learner’s strengths, weaknesses, and learning pace before designing a personalized study plan. I specialize in Algebra, Geometry, Statistics, and problem‑solving techniques, and I incorporate exam simulations, guided practice, and step‑by‑step explanations to ensure strong mastery of concepts. I also integrate mental math exercises, math tricks, and real‑life applications to make lessons more interactive and enjoyable. Whether a student needs help with homework, exam preparation, practice drills, or concept reinforcement, I focus on building strong foundations and logical thinking skills. I encourage questions, promote active participation, and create a supportive learning environment where students feel comfortable making mistakes and learning from them. Above all, I am committed to helping students reach their academic goals and become confident, independent learners who can succeed in Mathematics and beyond.

Mathematics concepts taught by John Rey
The session provided an introduction to algebra, focusing on solving quadratic equations by factoring. The Tutor first assessed the Student's foundational skills in linear equations and the distributive law, then proceeded to explain the standard form of quadratic equations, the concept of factoring binomials, and the zero-product property. The Student practiced identifying coefficients, applying integer rules, and solving for 'x' in various quadratic equations.
