QUASAR EDU — Terms

Last updated: 2026-10-10

What QUASAR EDU is

QUASAR EDU is an independent Cambridge IGCSE practice tool — Biology (0610, Extended) is the public subject; other subjects are in a closed pilot or still in development and are not sold. It generates exam-style questions from content you provide and marks your answers with AI-assisted, examiner-style marking. Where no official mark scheme exists, QUASAR constructs one and labels it as constructed. It is not produced, endorsed, or affiliated with Cambridge Assessment International Education. Diagrams are AI-generated and have not been independently verified against official Cambridge diagrams — treat them as a study aid, not a reference source.

No guarantee of results

AI-generated questions and AI-generated marking are a study aid, not a substitute for an official examiner, teacher, or past paper. QUASAR EDU does not guarantee any particular exam grade or outcome. Always cross-check against your syllabus, teacher, and official Cambridge past papers/mark schemes.

Free usage limits

Free accounts have daily generation and evaluation limits, enforced server-side to prevent abuse. These limits exist to keep the product sustainable, not as an arbitrary restriction — they are set well above what a genuine student needs in a normal study session.

Premium, billing, and refunds

Premium is a paid subscription processed entirely by Gumroad, our payment processor. Gumroad handles checkout, receipts, and cancellations directly. For a refund or billing dispute, contact Gumroad support first (they process the actual transaction), or write to us at 2146quasar@gmail.com and we will help. A refunded or charged-back purchase deactivates Premium access.

Your content

You are responsible for the content and answers you submit. Do not submit content you don’t have the right to use, content containing other people’s personal details, or content unrelated to Cambridge IGCSE study. We may rate-limit or block usage that abuses the service. When you upload your own question (text, photo or PDF), QUASAR marks it against a mark scheme it constructs from that question, or shows only the scheme when it cannot mark that kind of question yet. A constructed scheme is labelled as such and can be wrong; check it with your teacher.

Changes

QUASAR EDU is an actively developed pilot product. These terms and the underlying product may change; material changes will update the “Last updated” date above.
