DuckQuackPrep is an informal name students sometimes use for a set of free, browser-based test-prep tools and study resources—practice quizzes, flashcards, and short lessons—focused on K–12 and early college subjects. “Unblocked” versions refer to copies of these resources or similar sites that can be accessed at school when administrators have restricted or blocked the original sites.
