Sean S. passed a background check on 11/22/13. The check was ordered by Sean through First Advantage. For more information, please review the background check information page.

After sending a message to Sean, you will be able to order a new background check for $7.99. As part of your tutor selection process, we encourage you to run updated background checks. Please also review the safety tips for hiring tutors.

Are you searching for a math tutor? Maybe you need assistance with Calculus, or perhaps you are simply looking to refine your knowledge for an upcoming university entrance exam. I have the over twenty five years experience teaching and tutoring students, from ages 8 to 64, on topics including mathematics, physics, and astronomy.

When I first meet the student, my immediate goal is to determine in which topics they are having difficulty. I speak to the student, whatever age, as a person. Not necessarily as a peer, but always with respect -- and my students respond appropriately. Usually, a genuine rapport develops, which is the first step to gain the student's trust. During this time, I also gain insight into how the student learns (visually, audibly, kinesthetically), and what might be likely stumbling blocks, such as resentment towards authority, or a strong fear of failure.

I am usually able to quickly determine which gaps exist for the student in the subject matter. I ask questions about their knowledge and present problems to test their abilities. While the student works on increasingly challenging questions that I pose, I review their textbook and other materials for official curriculum needs.

When gaps become clear, I try to fill to most basic ones first. For example, many times I have found a students unable to explain multiplication. In response, instead of handing over a times table, I bring a blank times-table, and ask the student to fill it in. When finished, I ask the student to point out patterns, and to explain what they have learned.

By the end of the first session, the student has gained understanding of concepts, while I have learned about the student's knowledge and what steps must next be taken. I will occasionally assign a little homework (never very much) to the student, usually straight from their textbook. I also often assign myself homework -- to review material for the next session, and to prepare examples for the student to consider. I make known to the student what homework I will be completing, and ask the student to recommend more. (The students appreciate that I get homework, and love assigning some to me!!)

I assure you that if you select me as your tutor, you will not be disappointed. I look forward to working with you.

Algebra is the generalization of arithmetic. Where before a student learns 2+3 and 3*5, algebra allows for circumstances when a number is not known -- and often to solve such situations.

Lines are thoroughly reviewed in algebra 1. I show students how linear equations occur in their lives, and how to understand both their graphs and their equations. The course also covers polynomial basics and a detailed review of the parabola.

Algebra 2, sometimes called precalculus, is a more complex review of algebra. Polynomials are studied in detail, specifically finding its "zeroes". I show students what the problems really ask, and the techniques to solve them.

This class usually introduces trigonometry, a detailed study of circles. This course also goes into the relationship between parabolas and circles, and the equations and graphs of all conic sections.

Whereas algebra is the study of variables, numbers that change, calculus is a study of how variables change -- their rate of change, to be specific. As an analogy, algebra can tell you the average speed of a rocket ship, but Calculus can tell you its exact speed at any time, just like an odometer. I show my students how Calculus is found nearly everywhere, including in business, medicine, and nature.

Differential equations was a basic requirement for me as a mathematics major at college. I enjoy the challenge of tutoring this course. Differential equations is the subject of discovering solution functions to the given rules of how equations behave. I find this subject to be fascinating, and I work to covey the meaning of the equations to my students, as well as understanding how to obtain the solutions.

Geometry is based on points, lines, and angles, but mostly logic. A question like "Why do the angles of a triangle add to 180°?" can be answered very early in a geometry class using the basic concepts of a straight angle. Other concepts build upon this, such as: "The sum of the exterior angles of a polygon is 360°." I explain how these concepts are viewed and how viewing them in right order shines light onto the entire course.

If necessary, I cover the format of the GMAT and the question types of the Integrated Reasoning and Quantitative Sections. Then I explain specific strategies for the different question types, which we return to as we cover both the math fundamentals and specific questions. In particular, several question types are reviewed in depth, since many are likely to occur once.

To do well on the quantitative sections of the GRE, you must know more than just the mathematics of algebra and geometry. The newly revamped test has four types of questions on the Quantitative sections. These questions will require out-of-the-box thinking, beyond the skills taught in high school. I have been reviewing these question types, and have found strategies for them. Along with the math, I will teach you the format and how to successfully navigate the questions you that will confront you.

Arguably the single most important software ever developed, the spreadsheet is indespensible in any business endeavor. Its applications are extraordinary, and powerfully revealing information can be gleaned from data by even a moderately experienced user.

I explain the very basics of MS Excel, including proper keyboard use so students learn quickly and efficiently. Then I teach "cut, copy, paste" along with basic functions, and how to quickly fill a column or row with data. Other functions are taught to collect and alter data, and formats are explained to show information in nearly any way imaginable.

I help students understand prealgebra by reviewing the basics of arithmetic and introducing concepts of generalization. For example, imagine you travel 4 mph faster on your bike than I do on mine. What speed are you going if I am going 12 mph? What's my speed if you're going 9 mph? These sorts of questions introduce concepts to students, concepts that build to the idea of a variable, a letter that is used for any unknown number.

Precalculus is Algebra 2 or Algebra 3, because it includes the final study algebra prior to Calculus. Polynomials are studied in detail, including finding real and complex "zeroes" from Descartes' Rule of Signs.

Also studied is trigonometry, the study of circles. I teach this in very clear terms, using circular props so students can visualize the sine and cosine waves. This course often ends with limits and an intro to the rate of change of a function, such as speed.

I have taught the Mathematics portion of the SAT numerous times in the past, to groups and individuals. (I have created a workbook to assist students, which I am currently updating.) If needed, I first focus first on the format of the exam, and how to take advantage of the question types. Then I go over the content and the math needed to understand. Throughout, I discuss solving strategies with the student, so that they understand what to expect and how to approach the questions.

Trigonometry is a detailed study of circles. Imagine a point on a circle, as the circle slowly turns. How does the point move as the circle moves? What is its height from the center, and left-right distance from the center? The study of trigonometry often involves graphing trig functions, the study and graphs of inverse trig functions, and trig identities. I explain these concepts and others in a straightforward manner, so students can see the basic functions and why they are studied.

Great Tutor! Excellent Communicator! — Sean was absolutely EXCELLENT! He has an uncanny ability to turn difficult math concepts into something the average learner can understand. I highly recommend Sean to anyone that needs help with GMAT Quant., Geometry, Trig, and Calculus. He helped me get a great score on the GMAT Quant. and I am so grateful for his help. ...
