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.

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...

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.

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."

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.

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.

Very experienced and knowledgeable

Dave has excellent content knowledge, especially as it pertains to the math portion of the GRE. I am a complete Math illiterate and found he had a very good way of simplifying problems/test questions. As he has worked with many students in the past, he has created a very smart system for how to tackle the GRE, not only with regagards to practicing math itself, but also in terms of practicing a different mindset as one practices math. Excellent tutor.

Knowledgeable and very patient!

Dave helped me to understand regressional modelling and decision tree analysis. He is an excellent tutor with the ability to explain complex themes in simple language. Thank you very much Dave!

Vlada, 6 lessons with Dave

very helpful tips!

Dave was very kind and patient during our session! He even took the time to go over useful test preparation tips for the GRE that I would not have known without him! Definitely recommend to others studying for the GRE.

Knowledgable and excellent at explaining!

My daughter had a great first tutoring session with Dave. They jumped right in together and she received thorough explanation, moved through all of her questions efficiently and she walked away feeling confident!

"A hidden gem"

Dave S. fundamentally changed how I took the GRE. His unique insights into how the test is constructed resulted in instant improvements to my score. I was stuck in a rut with my quant score and tried other tutors on my own to teach me the material. But Dave teaches you how the test works, which is far more important in my opinion. I would recommend him to anyone else I know preparing for the GRE, he is a hidden gem on this site.

William, 3 lessons with Dave

Incredibly helpful!

I love working with Dave, he explains everything so clearly! I was having difficulty with a statistics concept, and Dave addressed it with great skill. He is also passionate about the subject, which makes him very enjoyable to work with.

Very helpful tutor

I spent hours trying to work out a probability concept before contacting Dave. Dave explained it very clearly and quickly. It is truly incredible how skilled he is at explaining statistical concepts. I highly recommend him!
