Editorial interest 79/100 Selection signal · not a rating of the site

An AP Macroeconomics learning resource with interactive graph labs, practice activities, and an exam-score calculator.

Landing page captured for the 2026-09-30 issue.

For: AP Macroeconomics students and teachers
Worth noticing: The course outline spans six units, from scarcity and supply to exchange rates, with 113 labs, drills, and quizzes listed.

Field notes

The course outline names topics by AP unit and subtopic, including automatic stabilizers, the loanable funds market, and international capital flows. A sample live graph uses Constant OC and Increasing OC controls, while the score calculator accepts multiple-choice and free-response points. The homepage labels the resource CED-aligned; that alignment is a site claim.
