Desmos-First
On the SAT's math section, students can use a graphing calculator called Desmos to help them with nearly every single question. Yet for some reason, SAT prep pretends it doesn't exist. There is using Desmos, and there is USING Desmos. With this course, you'll be able to raise your score by upwards of 50 points simply by utilizing a tool you've had all along.

It is worth reading Module 3 early
The failure mode this course is built to avoid is the student who picks up twelve tricks and starts reaching for the calculator on every question, including the ones where a pencil would've been four times faster. Knowing when not to graph is part of the technique itself.
The recipes, all 1,421 practice questions, and every worked explanation come from Miyagi's internal tutor taxonomy and question bank, which scores roughly 62% of the SAT math bank as having a Desmos-first route. Modules 0, 2, 3, and the Triage page are written from SAT-tutor video transcripts and the r/SAT Official DESMOS Thread.
