AP® is a trademark registered by the College Board. StudyLoop is an independent, student-led educational project. We are not affiliated with, sponsored by, or endorsed by the College Board.

Original content

Every question, lesson, and worked example on StudyLoop should be original. Nothing should be copied, paraphrased, or adapted from College Board released items, AP Classroom, CBSE/NCERT materials, SAT materials, textbooks, or commercial prep platforms. If an item resembles copyrighted material, it should be retired and rewritten after confirmation.

AI disclosure

Questions may be drafted with AI assistance and reviewed by a human before publication. AI does not grade your answers. Current multiple-choice items are checked by deterministic code; free-response items use self-grading rubrics; future algebraic answers should be verified for mathematical equivalence using SymPy or an equivalent symbolic system.

Items carry visible badges showing the level of human review: "Needs mentor review" (alpha content), "AI-reviewed" (founder spot-checked), or "Verified by [Mentor]" (subject teacher signed off). You can always see which level of review an item has received.

Open educational resources

Where helpful, we link to external open resources such as OpenStax textbooks and PhET interactive simulations. We do not republish their content. Those resources are licensed under Creative Commons and remain the property of their respective creators.

Not a substitute for school instruction

StudyLoop is a study companion. It does not replace classroom instruction, a laboratory science requirement, or the guidance of a qualified teacher. Use it alongside your school's curriculum, not in place of it.

Local nickname profiles

Nickname profiles are local browser memory, not real accounts. They are meant to separate progress, saved errors, and review status for different students using the same device. Do not use real names. Clearing browser data may delete this local progress.

Limitation of liability

We do our best to provide accurate, useful practice content, but errors may exist. Your performance on the actual AP exam depends on many factors beyond your use of this site. StudyLoop and its contributors accept no responsibility for exam outcomes or for decisions students or families make based on practice results.
