Probably the best math tutor in the inland empire. Experienced and professional, he was able to diagnose my deficiencies in math and immediately start towards correcting them. I worked with Kevin for about eight months and my SAT national ranking went from the 71st percentile to the 99th percentile. He has bookshelves and folders full of materials on integrated math, algebra, pre-calculus, calculus, trigonometry — he’s proven to be thoroughly familiar with effectively every math subject taught in high school and knows how to teach all of them. Would recommend.
