I’m a Virginia Tech architecture professor (with a math degree) who’s been volunteer tutoring in public schools since I was in middle school. If you're interested in The Olive Book, I know that you probably:  

are a visual learner

are a busy person

remember content better when it is told with a story

never had a bad class with a good teacher

find the SAT and ACT tests overwhelming.

And I know that I can help.

In Olive Book's courses,

You'll engage in practice questions with animated answer explanations.

You’ll study for less time because we prioritize the content most likely to be on the test—and the content most likely to give you trouble.

You’ll get everything you need for the test in this one course (no other study material needed)—seriously.

You’ll automatically give a student in need free access to the course when you enroll.

You’ll earn a higher score: currently by an average of 160 points (SAT) and 2.3 points (ACT).

If you are not thrilled, you’ll get your money back (no questions asked, no fine print)

We're professors, tutors, and teachers, and our mission is to provide you with the best test prep materials so you can own the test. Content first!

For more information about us, or for any questions or concerns, send us an email here.

Ben Orlin

Course Content Creator

Ben Orlin develops math content for The Olive Book. A math teacher and author, he tells a lot of jokes (a few of which are actually decent) in the hope of helping those who feel alienated from mathematics.

His books Math with Bad Drawings (2018) and Change is the Only Constant (2019) explore mathematics through cartoons and storytelling. His blog Math with Bad Drawings has attracted millions of visitors since 2013, with approving mentions from Vox founder Ezra Klein, poker champion Annie Duke, and mathematician and former NFL player John Urschel, among many others. 

His writing has appeared in The Atlantic, Slate, The Los Angeles Times, and elsewhere. He has taught middle and high school math in the U.S. and the U.K. He now considers writing his day job and teaching his passion project.

Ralph Hale

Ideation & Implementation Coordinator

For his work with The Olive Book, Ralph is the resident jack-of-all-trades. Content editing, proofreading, graphics design, and operational strategy are all occasionally known to visit his wheelhouse. Around the office, he's probably best known for his turning of phrases, love of recipe tuning, and capacity to turn around solutions to complex, multifaceted challenges.

These duties mesh well with his engagement in playing his eclectic interests off one another; when asked to list a sample of them, he said, "Things". We know he folds origami, paints, fixes anything and everything that crosses his path in need of repair, and produced a book that was an amalgam from his pursuits in photography, literature, geometry, communication, printmaking, botany, graphics, assembly, music, food, and wonder. The book is also a passable slinky.  

Ralph has his B.Arch from Virginia Tech and is walking the meandering path toward architectural licensure.  

Amy Vogelaar

Director of Technology, Course Content Contributor

Amy Vogelaar graduated Virginia Tech with a BA in Professional Writing. She was hired on as a writer and editor for an updated version of The Amber Book workbook. When the idea came up for an Amber Book e-course and an additional Olive Book course, she revealed her website experience. She now manages the course site(s).

She is the person in the office most likely to end up drawing attention with her not-so-silent dance of triumph after solving a particularly complex problem. Her favorite pastimes are traveling and exploring other cultures, theater and dancing, and spending time lazing about her house with a good book and her two rambunctious kittens, Roxie and Toulouse.
