Online Math Tutor with a PhD with over 5 years experience

I started teaching math to undergraduates when I was in the second year of college. By the time I started college, I had taught over 100 students and most of them helped me reach the 90's on all math tests. Between college and graduate school, I tutored about 20 to 30 hours a week. All my clients came by word of mouth. During this time, I have grown and expanded as a tutor. I got my PhD in Mathematics in 2005 and started working as a math professor and also started teaching SAT preparation cours...

I started teaching math to undergraduates when I was in the second year of college. By the time I started college, I had taught over 100 students and most of them helped me reach the 90's on all math tests. Between college and graduate school, I tutored about 20 to 30 hours a week. All my clients came by word of mouth. During this time, I have grown and expanded as a tutor. I got my PhD in Mathematics in 2005 and started working as a math professor and also started teaching SAT preparation courses. Over the next decade, I field-tested many strategies for standardized testing, and everything I learned went into my first SAT math preparation book, published in 2011. From 2011 to the present, I have written standardized test math books, teaching college math classes, conducting standardized test courses, and teaching math at a higher level. My passion is always math and education. As a doctoral mathematician, I have the math knowledge and skills needed to understand most math, including graduate courses and even math research papers. As an educator, I have a gift for transferring my mathematical knowledge to others. I have taught thousands of students about standardized exams such as the SAT, ACT, AP Calculus Exam, NY Regent Exam, and SAT Math Exam. In 2011 I published my first SAT math book and soon founded the company Get 800. Since then, he has published more than 20 math books for standardized testing. Many of my clients have fully standardized test results using only my books. I am currently a professor of mathematics at Hofstra University, teaching calculus, multivariable calculus, derivative equations, linear algebra, real analysis, and occasionally set theory.
