For schools
Every student now sits the SAT inside Bluebook, and Bluebook has a Desmos graphing calculator built into it. Nobody teaches them to use it. The ones who arrive already knowing it type a question in as it is written and read the answer off the graph. The rest do the algebra by hand while the clock runs. That gap tracks almost exactly with who could afford a tutor.
This course exists to close it. 27 short chapters, about ten hours, each one a video followed by practice inside a live calculator that marks itself. It is free, and it will stay free.
No cost, no ads, no paid tier, no upsell. There is no procurement process to start because there is nothing being sold.
No account is needed to look at the course, and we collect nothing from students who do not make one. No third-party tracking anywhere on the site.
Not affiliated with or endorsed by College Board or Desmos. We make no promises about anyone’s score.
Three sections. Twelve prerequisite chapters on driving the calculator at all, seven on answering questions off a graph, and eight on the regression trick that solves for an unknown constant without algebra. By our own estimate the method reaches 53.55% of SAT Maths question types — an estimate taken from our curriculum, not a score and not a promise.
Link it from a research guide, put it in a newsletter, hand it to a class, print the address on a board. You do not need our permission and we do not want anything back.
If you would rather we told you when something changes — a new chapter, a change to the test that affects the method — leave your address. That is the only reason we would ever write to you, and it is easy to stop.
