Bio

Hi, my name is Dave.

I have tutored hundreds of students. Although many came to me afraid of math, most of them left with a well-earned sense of confidence and mastery. You will too. I promise that you will learn what you want to know.

Hi, my name is Dave.

I have tutored hundreds of students. Although many came to me afraid of math, most of them left with a well-earned sense of confidence and mastery. You will too. I promise that you will learn what you want to know.

My style is personable, engaging, and easygoing. I have extensive knowledge of statistics, GRE and SAT test-taking, and problem-solving. I zero in on precisely what's giving you trouble, and will break each problem into pieces you can understand and learn. I am eager to work with students who are falling behind, as well as students that want to get ahead or explore outside of the normal curriculum.

While a graduate student at UC Berkeley, I received the University teaching award for statistics, and my undergraduate students consistently gave me the top rating in the department. While there, I tutored professors, grad students, and undergrads in math, advanced statistics and data analysis. I have also successfully tutored many high school students (though I prefer not to tutor students below high school level, and do not tutor calculus).

I have worked for both Kaplan and McGraw-Hill designing testing materials for tests such as the GRE, SAT, and ACT. I know the ins and outs of how tests are constructed and how to maximize your score, and am happy to share my knowledge with you.

I live in Hercules, and do not travel more than a few miles for tutoring. If you don't live nearby, I work online all the time, or you will need to come to me.

I thank you for your consideration.

Sincerely,

Dave

GRE

GRE

Math skills are but one facet of the GRE Quantitative section. If you've taken a practice test or two, you've already seen that problem-solving, your ability to gain insight into a problem, comprehending confusing problems, and avoiding errors are skills no less essential to achieving your best score. But these critical skills are rarely taught explicitly. With my help, you will not only learn but master them. I received a perfect score on the GRE Math, and I have worked for both Kaplan and for McGraw-Hill's testing division and know the ins and outs of how tests are constructed. And for those students who wish to go beyond merely acing the GRE to a deeper understanding of how to approach and solve truly difficult problems, that can be a central part of our work together. I'd love to prepare you for the GRE, for Grad School, and to flourish in your chosen profession.
Probability

Probability

I am very good at breaking down the concepts in Probability into pieces that are easy to understand and master. You will learn how and when to use each formula, and come to know not just how to solve each problem, but to understand what you are doing, why you are doing it, and how to make practical use of it later in life.
SAT Math

SAT Math

The SAT math section tests problem-solving and avoiding errors as much as it does math. These skills are essential to achieving your best score, but are rarely taught. With my help, you will master them, and also understand how they will help you to do well on the SAT and in college. I have worked for both Kaplan and for McGraw-Hill's testing division and know the ins and outs of how tests are constructed, and I got every question correct on my SAT Math.
Statistics

Statistics

I have taught and tutored students in statistics for eight years, and can explain even the most complicated statistical concepts simply, clearly, and effectively. For example, most of my fifteen current statistics students each came to me feeling very confused. But after a session or two, each one knows what they are doing, why they are doing it, and how to do it; it all makes sense. By the end of our time together, the most frequent comment I get is, "Wow, statistics is really easy."

Helps Stats make sense (and sometimes fun!)

Before I picked up Dave as my tutor, I had failed or dropped Statistics 3 times. I thought that I might just be plain bad at math and was considering dropping out of college entirely. Dave erased those thoughts from my mind in one lesson. Stats began to make sense, and sometimes were even fun! With Dave's patient tutelage I managed to pass my class and get my bachelor's degree. It would not have happened without him.

Great Tutor For College Statistics - A+

Dave helped my young adult son pass Elementary Statics With Probability with an A! Nothing short of amazing because my son had previously failed math and this class was the final requirement he needed to transfer to Cal Poly in the fall. My son said Dave helped put statistics in real world perspective by using real world application. He was good and explaining the concepts and why they existed. As a parent, I've never seen my son as confident each week going into tests and his final. Not only did he get his first 100% on a math test in his life but he passed the class with a A. I highly suggest Dave, especially for people who deeply struggle with math. Thank you Dave!

Brilliant SAT Math tutor!

Dave has tutored two of my sons to help them prepare for their SATs. Patient, professional, and extremely knowledgeable, Dave has a deep understanding of the test and is able to thoroughly explain the material in an easy way. He works alongside students through each problem, helping them to not only find the solution but also understand why they made mistakes along the way. Moreover, he helps his students learn the inner workings of the test and master strategies to excel. Dave developed a tailored approach with each one of my sons, allowing my older son to raise his score by 100 points, ultimately scoring 790 on the math section (and getting into his dream college!). My younger son is still in the process of working towards his final result and has already scored 780 in math on the last test (an increase of 60 points). Dave is friendly, approachable, and just a wonderful person. He has empowered my sons to believe in their success on the SAT and always made them feel happy and at ease during the sessions. I highly recommend Dave to anyone who is seeking a great SAT tutor!

Best math tutor!!

Dave was an awesome tutor for my son. He broke down difficult math concepts and explained things in very simple terms. He is absolutely the best math tutor my son has ever had. I just wish we'd found him sooner. Dave is also a very patient and kind person. Highly recommend!
