Questions
- What is included?
- All 30 modules of the course reader and every practice set linked from them, for the calculator built into the digital SAT.
- Do I need an account?
- Yes, and it is free. The account carries the 12-question diagnostic, which tells you which units you can skip before you are asked to pay for anything.
- Does this renew or charge again?
- No. It is $29 once, and you keep access for as long as the course exists. Nothing renews and nothing charges again.
- Will this help if I am already good at math?
- Yes. The course is not about understanding the math, it is about doing it faster. Strong students often gain the most time back, because they already have the algebra and just need the calculator moves.
- What if the test changes?
- The course covers the calculator techniques the digital SAT's built-in Desmos tool supports today. If that tool changes, we update the course to match, and your access carries over.
