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. References to AP course frameworks on this site are descriptive and used in good faith to help students find the right material for their exam preparation.

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, 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 revised through automated checks, reviewer passes, and founder review before publication. The aim is original practice that matches the style and rigor of the relevant exam without copying from published papers, textbooks, or commercial prep resources. 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.

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.

Student privacy and children's data

StudyLoop is designed for students, including students under 18. India's Digital Personal Data Protection Act, 2023 treats a person under 18 as a child and places special duties on anyone processing a child's personal data, including verifiable parental consent and restrictions on tracking, behavioural monitoring, and targeted advertising directed at children.

To avoid collecting student data during ordinary practice, StudyLoop does not require server accounts, passwords, real names, school names, phone numbers, server-side answer history, advertising trackers, analytics pixels, or behavioural profiles. Practice progress, drafts, saved mistakes, and nickname profiles stay in the browser's local storage on the device being used.

Feedback reports are the exception because they are deliberately sent to us for review. A report may include the page address, selected issue type, technical context, optional written details, and an optional email address if you choose to provide one. Students should not include unnecessary personal information in feedback; if you are under 18, use feedback with a parent, guardian, or teacher's knowledge.

Limitation of liability

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