Meet William Brubaker: GRE & GMAT Tutor.

William is a full-time, professional GMAT, GRE, and EA tutor with over 11 years of full-time tutoring experience. He has logged over 8,000 hours and is an expert in his field. His students have been accepted at Anderson School of Business at UCLA, Booth School of Business at University of Chicago, Columbia Business School, Darden School of Business at University of Virginia, Haas School of Business at U.C.

William uses proprietary database software and practice questions from official guides and major schools to help his students focus on the strategies and principles they need to know in order to do well on their exams. To identify their weak areas and focus on them more deeply, he employs data analysis to track his students’ performance on the application of the strategies and principles required to do well on the exam.

After the first lesson, William evaluates the student’s proficiencies in the main categories and from then on uses materials that are likely to advance those proficiencies. He assigns homework after each lesson, consisting of reviewing explanations to practice questions the student missed in the previous meeting, flashcards to memorize GMAT idioms or GRE vocabulary words, new and previously missed practice questions, and a report of the strategies and principles and the number of times the student has missed them. In each subsequent meeting, William reviews the homework with the student.

William has received numerous positive reviews from past students, who have described him as a “phenomenal,” “patient,” “brilliant”, “awesome”, “effective”, “organized”, “thorough”, “amazing” and “knowledgeable” tutor. His tutoring method has helped many students raise their scores and achieve their desired results.

William earned degrees in Architecture and Business at the University of California at Berkeley.
