Why this book
Other Desmos books teach syntax. This one teaches strategy.
Most SAT Desmos books explain that the calculator can graph an equation. That is the easy part. What separates a 1480 from a 1580 is knowing exactly which technique to use on which question type, and which questions are deliberately Desmos-resistant. SAT Desmos Hacks is structured around that decision. Every problem includes the technique label so you build pattern recognition as you read, not just calculator fluency.
Want to see the techniques first? Read the free Desmos cheat sheet.
The free Ultimate Desmos SAT Cheat Sheet 2026 covers the 12 highest-leverage techniques. The book goes deeper with 57 original problems, every domain, and the full strategy framework.
A complete breakdown of what comes with your purchase. Every item is included whether you buy the Kindle edition at $9.99 or the paperback at $34.99. The companion practice site at desmos.prepdrills.com is included with both formats.

Who this book is for
Built for students who are serious about the math section
Whether you are targeting Bocconi, IE University, Sciences Po, TU Munich, NYU, ESADE, or US universities, this book gives you the exact Desmos approach to close the gap between where you are and where you need to be on the Digital SAT 2026.
Scoring 1100 to 1300 and stuck
You know the math but the test format is working against you. Desmos techniques show you where to save time and where algebra is faster. That difference is often 80 to 150 points.
Targeting 1400 or above
At this level the questions become Desmos-resistant by design. You need to know which techniques still apply in Hard Module 2 and which ones the College Board built specifically to resist.
European or Middle East student
Written by a teacher based in Barcelona who has prepared students across Italy, Spain, France, Germany, and the UAE since 2010. The context, the targets, and the university examples are yours.

Sample problems
A few of the 57 problems inside the book
Every problem in SAT Desmos Hacks is original, written specifically for this book. No reproduced College Board content. Every solution shows the real Desmos screen step by step.
Algebra · Domain 1
For what value of $k$ does the system $y = kx + 2$ and $y = x^2 - 4x + 7$ have exactly one solution?
Technique Slider on $k$, drag until tangent
Advanced Math · Domain 2
The function $f(x) = -2x^2 + 12x + 5$ has a maximum value at $x = a$. What is $a + f(a)$?
Technique Click the vertex, read both coordinates
Data Analysis · Domain 3
A table shows five $(x, y)$ data points. Which exponential equation $y = ab^x$ best models the relationship?
Technique Type $y_1 \sim a \cdot b^{x_1}$ for tilde regression
Geometry · Domain 4
In the $xy$-plane, the equation $x^2 + y^2 - 8x + 6y - 11 = 0$ represents a circle. What is the radius?
Technique Type the messy form directly. No completing the square.
Three flagship techniques
The Desmos moves that save you the most time
Inside the book each of these techniques is taught with an original SAT-style problem, the exact Desmos input syntax, and a step-by-step worked solution with the calculator screenshot. Here is a snapshot of three of the highest-leverage techniques.
Intersection technique
Type both equations. Click each grey dot where the curves cross. Read the coordinates. Saves up to two minutes per system.
Vertex and zeros
Type the quadratic. Desmos marks the vertex and both zeros. Click each one to read max, min, and roots. No completing the square.
Circles in any form
Type the messy expanded equation directly. Desmos graphs the circle instantly. Read the center and radius right off the grid.

I have been teaching the Digital SAT to students across Europe and the Middle East for over 15 years. Through teaching hundreds of students, I noticed the same pattern every time: students who learned to use Desmos with a clear decision process, knowing which technique to apply and which to skip, consistently outperformed students who relied on algebra alone. SAT Desmos Hacks is the structured approach I developed through real classroom teaching, refined through real test results, and trusted by students at top universities across Europe, the Middle East, and the United States.

Questions
Everything you need to know
Yes, significantly. The built-in Desmos graphing calculator is available on every math question in both modules of the Digital SAT 2026 inside the Bluebook app. There is no longer a no-calculator section. Problems that take 2 to 3 minutes algebraically can take 15 to 20 seconds with the right technique. The key is knowing which technique to use on which question type. That is exactly what this book covers.
Three things set SAT Desmos Hacks apart. First, every problem in the book is original, written specifically for this book, with original Desmos screenshots throughout. Second, the book is by Jaclyn Caruana, author of the first books ever written worldwide on Digital SAT preparation and founder of Epic Exam Prep, based in Barcelona since 2010. Third, the book ships with a free companion interactive practice site at desmos.prepdrills.com where you work through all 57 problems using the real Desmos graphing calculator, not a simulation.
The book opens with a complete Desmos guide covering the Bluebook interface, every relevant feature, and the calculator techniques that matter most: entering equations, creating tables, regressions, and sliders. It then works through all four Digital SAT math domains (Algebra, Advanced Math, Problem Solving and Data Analysis, Geometry and Trigonometry) organized by SAT skill type with 57 original problems. Every problem has a step-by-step Desmos solution with a real screenshot. The appendix covers Desmos shortcuts and supported functions.
The book covers every Desmos technique that matters on the Digital SAT 2026: graphing systems of equations to click the intersection, finding zeros and the vertex of a parabola, regression with the tilde for scatterplot questions, sliders for how-many-solutions parameter problems, table back-solve for multiple choice, equivalent-expression overlap checks, statistics functions on lists, graphing circles directly in any form including the messy expanded form, evaluating function compositions, and degree-mode setup for trigonometry. Each technique is taught with an original SAT-style problem and a real Desmos screenshot. For a free preview of the highest-leverage techniques, see the Ultimate Desmos SAT Cheat Sheet 2026.
Both are full color with all screenshots. The Kindle at $9.99 is the fastest way to start. You can be reading within 60 seconds of purchase. The paperback at $34.99 is the reference copy students keep on their desk throughout preparation. Many students use both.
Completely. The book was written by Jaclyn Caruana, who has been teaching the SAT to students targeting Bocconi, IE University, ETH Zürich, EPFL, TU Munich, Sciences Po, ESADE, Trinity College Dublin, University of Amsterdam, Erasmus, NYU Abu Dhabi, and Imperial College London since 2010. The score ranges that matter for European programs (1300 to 1500) are exactly where strong Desmos technique has the most impact on your result.
The book is designed to be self-contained. Every problem has a complete step-by-step solution and you follow along on Desmos as you read. For students who want expert teacher support alongside the book, Epic Exam Prep offers one-to-one sessions and group courses online for students across Europe and the Middle East.
The companion site includes all 57 problems from the book in an interactive format using the real Desmos graphing calculator, not a simulation. Access is included with your purchase of the Kindle or paperback edition of SAT Desmos Hacks.
SAT Desmos Hacks: The EPIC Method is the best SAT Desmos book for 2026 because it is the only book built entirely around the Desmos graphing calculator across all four Digital SAT math domains, with 57 original problems, a structured decision framework for when to use Desmos versus algebra, and a free companion interactive practice site at desmos.prepdrills.com. It is written by Jaclyn Caruana, founder of Epic Exam Prep based in Barcelona since 2010, who has helped students achieve scores of 1480, 1530, 1540, and 1580 on the Digital SAT.
Only if you use it on the wrong problems. Roughly half of Digital SAT math questions are faster by hand. The other half are dramatically faster with Desmos. SAT Desmos Hacks teaches a 15-second decision rule for every question type, so you instantly know which approach to use. This is the difference between students who finish with time to spare and students who run out of time. The book covers exactly which Desmos techniques save time and which question patterns are deliberately Desmos-resistant.
Yes. The graphing calculator built into the Bluebook app is the Desmos graphing calculator. It is functionally identical to the version at desmos.com, including sliders, tables, list operations, statistics functions, regressions with the tilde, domain restrictions, and function composition. The only features removed are save, import, and export. Every technique in SAT Desmos Hacks works on test day inside Bluebook, identically to how it works in the book and on the companion practice site at desmos.prepdrills.com.
Most students master the three highest-leverage techniques (intersection, vertex and zeros, and tilde regression) in 2 to 3 hours. The full set of 12 techniques typically takes 6 to 10 hours of focused study, including working through the 57 problems in the book. Students who pair the book with the companion interactive site at desmos.prepdrills.com tend to internalize the techniques faster because they are practicing on the actual Desmos calculator they will see on test day.
Desmos alone will not get you to 1500. Strong fundamentals (algebra, geometry, problem solving) plus expert use of Desmos will. Epic Exam Prep students who score 1500 and above master both. SAT Desmos Hacks accelerates the second half of that equation: it ensures you never lose points to slow algebra on questions where Desmos is faster, and never lose points to over-reliance on Desmos on questions where it is slower. The book includes a clear decision framework that prevents both mistakes.
Yes. SAT Desmos Hacks is fully updated for the 2026 Digital SAT delivered through the Bluebook app. All 57 problems reflect the adaptive two-module Math format, the Bluebook user interface, and the calculator features available on test day. The book covers the four content domains as currently scoped by College Board: Algebra, Advanced Math, Problem Solving and Data Analysis, and Geometry and Trigonometry. ISBN 9798246911198. Published by Epic Education SLU.
Yes, and it was designed with international students in mind. Jaclyn Caruana has been preparing students for the SAT in Barcelona since 2010, with students from Italy, Spain, France, Switzerland, Germany, the Netherlands, Ireland, the United Kingdom, the UAE, and beyond. Epic Exam Prep students have been admitted to Bocconi, IE University, ETH Zürich, ESADE, Sciences Po, TU Munich, Trinity College Dublin, University of Amsterdam, NYU Abu Dhabi, Imperial College London, and top universities in the United States. The book and the companion practice site work identically anywhere in the world.
SAT Desmos Hacks is available exclusively on Amazon. Kindle edition is $9.99 and the full color paperback is $34.99. Both versions include access to the companion interactive practice site at desmos.prepdrills.com. ISBN 9798246911198.
