- Cost
- Free. No account is required for any student feature, and there are no ads. Teacher classroom tools are free for a pilot semester, then $15 per student per year.
- Format
- Interactive. 17 draggable graph sandboxes, 111 draw-the-graph FRQ scenarios graded from the geometry of what the student draws, 36 calculators, a 624-term glossary, 108 written study guides, practice questions and flashcards.
- Covers
- AP Microeconomics and AP Macroeconomics in full, mapped to CED topic codes, plus IB Economics, A-Level, on-level high school economics and intro college. Worked answers to the released 2025 and 2026 AP free-response questions.
- Best for
- The best graph practice available anywhere for AP economics, because it is the only graph practice that is actually checked. The grader compares every curve position before and after and marks the answer correct only if the required curve moved in the required direction and nothing else moved, which is the same standard a reader applies to a hand-drawn exam graph. No other tool here grades a drawn diagram.
- Not built for
- It is built for doing rather than watching: instruction is written and interactive, and every graph is something a student manipulates or draws rather than observes. It runs in any browser with nothing to install, and it covers economics only, in full depth, rather than spanning subjects.
