OlympiadPilot Turns 2,600 AMC Problems Into a Practice Route

Field notes

The archive is organized both chronologically and conceptually: visitors can open a specific AMC 10 or AMC 12 contest, or work through areas such as geometry and number theory. The homepage lists 1,300 problems for each exam family and breaks algebra into 40 concepts, while a separate technique section covers methods including casework, symmetry, invariants, and bounding. It also describes answer checking, written solutions, and attempted-problem tracking.
