Engineered GMAT and GRE Prep by U.C. Berkeley Grad
I am a full-time, professional GMAT and GRE tutor. I have logged over 4,000 hours on the Wyzant platform and I consider myself an expert. Developed over seven years of full-time tutoring, my tutoring approach is based on the impediments that have prevented my students from answering questions correctly. Each of those impediments became an underlying principle, and each principle has two parts: the situation that requires my students to use the principle, and what to do in that situation. ...
I am a full-time, professional GMAT and GRE tutor. I have logged over 4,000 hours on the Wyzant platform and I consider myself an expert. Developed over seven years of full-time tutoring, my tutoring approach is based on the impediments that have prevented my students from answering questions correctly. Each of those impediments became an underlying principle, and each principle has two parts: the situation that requires my students to use the principle, and what to do in that situation. Principles are variously formulas, theorems, number properties, shortcuts, processes, traps, idioms, grammar rules, argument analysis approaches, plan analysis approaches, approaches to various critical reason question types, reading passage types and associated pitfalls to avoid, etc.
I use practice questions to teach the underlying principles because research shows a major advantage to that method as compared with lecturing or reading about them in books. Each question is accompanied by a step-by-step explanation, with each step based on an explicit underlying principle. After each lesson, the explanations covered during the lesson are made available for my students to review before the next lesson.
After my student has reviewed those explanations and several days have passed, those questions will be assigned again as homework. Any of those that the student still cannot be answered correctly will be discussed again in the next lesson, and this will continue to occur until the student can correctly answer the question.
During each lesson, we work together on questions that are based on at least one underlying principle that the student has not previously encountered during a lesson; questions that are based on principles that the student has encountered previously become homework questions. As with previously missed questions, any new question that the student misses will be discussed in our next lesson.
About half of the questions I use are from a recent GMAT Official Guide and the other half are from the four major schools. A few are from one of the popular online question banks.
Every question is rated as the percent of my students who missed that question the first time. As we work through questions together each correctly answered question is followed by a more difficult one, and vice versa. This is done so that we are always working at the optimal level of difficulty for that student. Since research shows better outcomes when material is mixed rather than presented in blocks, I use that approach.
The underlying principles are the core of the process. I provide my students access to flashcards for all principles the student has encountered to date, and with explanations that are based in part on any given principle.
Very knowledgeable and helpful

We went over some quant math and some basic tools and techniques. He is very patient. He has an online system to track your progress and trouble areas. Looking forward to the next lesson and learning more tricks.Zoe, 1 lesson with William
Best tutor I've ever had.
William is an excellent tutor. He goes out of his way to make sure I understand each problem before moving on. William has incredibly effective teaching methods, including reviewing and practicing problems as "homework". My practice tests have improved significantly since I began tutoring with William and my GMAT test will show these same improvements. Highly recommend.Ryan, 8 lessons with William
Excellent GMAT Platform
William is a very patient and knowledgeable teacher, he takes the time to teach each new topic as they come up. He allows you to utilize an efficient and effective study plan to supplement your own. I have had several sessions with him and would highly recommend him!Evan, 9 lessons with William
Very patient and easy to understand
William helped with my GMAT Quant section. He reviewed data sufficiency questions as well as helped me to refresh my algebra and probability problem areas. He was indeed very patient and questions were directed at figuring out my knowledge base and building from thereNando, 3 lessons with William
Very knowledgeable, very patient GRE tutor
William is helping me VERY much with the math portion of the GRE. It's been 15 years since I've done high school algebra and geometry, and I've forgotten almost all of it. He's tailored his lessons for exactly where I'm at, and even assigns extra practice in between tutoring sessions to help me catch up. So grateful for his help!Elizabeth, 7 lessons with William
Knowledgeable and Patient Tutor
Thus far, William has honed in on my weaknesses and helped me mitigate the behaviors that are detrimental to scoring in the 700s. I look forward to my continued work with William.Pat, 7 lessons with William
Excellent tutor with real GMAT knowledge and individually tailored lessons
I took about a dozen lessons with William over the course of two months, and he helped me pull my GMAT score up from 660 to 710, with what felt like minimal effort from me. His online meetings work great, and he tailors the questions you receive so that they are appropriately challenging. He also provides optional homework, so that the lessons can be spent reviewing questions you know you need help on, rather than just working on questions with him there if you need him. He has great insight and tips for the GMAT, and I doubt there is a better instructor out there.John, 10 lessons with William
