Looking for a math tutor near you? I’m Dr. Harry Singh, PhD, a dedicated math tutor since 2008, specializing in Grades 5 – 12 math tutoring, including SAT and ACT math preparation. My goal is to make math enjoyable, accessible, and affordable, helping students build confidence and a strong understanding of core and advanced math concepts.
I earned my PhD in Aerospace-Nonlinear Optimization and MS in Applied Mathematics from the University of Maryland, College Park, MD. With expertise in advanced mathematical techniques, I provide students with practical problem-solving strategies and clear guidance on challenging topics such as calculus, algebra, geometry, trigonometry, and optimization. My experience allows students to master complex math concepts efficiently while developing confidence and critical thinking skills.
My approach is centered on making math approachable, engaging, and practical. I focus on:
1) Building strong foundational skills
2) Tailoring lessons to individual learning styles
3) Connecting complex concepts to real-life applications
Students learn to excel in algebra, geometry, trigonometry, calculus, and more, gaining the skills and confidence needed to succeed in school and standardized tests like the SAT and ACT.
I’ve helped students across the Bay Area, including Richmond, El Cerrito, Berkeley, and beyond, improve their math grades and test scores. Many have excelled in SAT and ACT math sections, and my personalized guidance has supported students in gaining admission to top universities, including Harvard, University of Chicago, University of Pennsylvania, Stanford, and UC Berkeley.
Huge thanks to Math Bumble for helping me get a 36 on the ACT math. They also helped me with my Precalculus topics for school. The tutoring is super clear and tailored to focus on what you specifically need help with!

Truly an outstanding math tutor! His step-by-step explanations of limits, derivatives, and integrals is incredible. The assignments given are really great to understand the concepts. Thanks to him that I feel comfort in my AP class.

Awesome teacher! He explains math in a way that makes everything so clear. His in-class questions are really helpful to understand the concepts. He’s really patient and never gets annoyed when we ask questions.

Mr. Harry is the best tutor! He always finds practical ways to teach math, and his examples make sense. He’s super friendly and always makes sure everyone gets it. I really enjoy his class!

Mr. Harry is super nice. He helped me understand fractions so well and now I can solve them fast. I will continue to learn math with him for the future.

He makes tough math topics like algebra and geometry easy to understand. His explanations are clear, and easy to understand. I’ve improved so much in class and feel more confident tackling problems.
