Each subject is 12–24 progressive levels. Here's how levels map to grade for Math and science tracks.
| Grade | Age | Math levels | Example topics |
|---|---|---|---|
| K–1 | 5–7 | Levels 1–4 | Counting, addition, subtraction |
| 2–3 | 7–9 | Levels 5–8 | Multiplication, division, fractions intro |
| 4–5 | 9–11 | Levels 9–12 | Decimals, ratios, basic geometry |
| 6–7 | 11–13 | Levels 13–16 | Pre-algebra, proportions, coordinate geometry |
| 8–9 | 13–15 | Levels 17–20 | Linear equations, systems, geometry proofs |
| 10+ / AP | 15+ | Levels 21–24 | Quadratics, functions, intro calculus |
Shorter tracks (Physics, Economics — 12 levels) compress this into half as many bands. See the full curriculum on the Features page.
