Build the Math skill. Make Desmos work for you.

Give the Math skills you find difficult more time to click, with focused questions, clear explanations, and Mica to help. Deepen your approach with 30 Desmos lessons built by Vertex’s in-house content team from an analysis of an archive of 1,900+ official SAT Math questions.

Explore the Desmos course

A course shaped by the questions students face.

Our in-house content team turned recurring patterns in official SAT Math questions into a comprehensive course in using Desmos. The five-unit sequence spans equations and systems, functions, geometry, trigonometry, and data, from the calculator’s controls to choosing an efficient method.

Work through examples, try each step, and check your understanding. Learn what to enter, what the result means, and when solving with algebra is the better move.

More practice where Math feels hardest.

Follow a daily focus shaped by your diagnostic and recent answers, or choose a skill you want to strengthen. Work through 1–20 questions at your chosen difficulty, check the reasoning, and ask Mica when you need help. Your saved and missed questions are there when you want another look.

Daily and custom practice are included with a card-backed trial or paid plan, within usage limits.
