Frequently asked questions
What can I find here?
Study materials listed for courses and universities in the current catalog. Search by course, subject, institution, or title.
Are materials verified by QMarketplace or a university?
No verification process is currently implemented. Review each listing's description and details before purchasing; do not assume a listing is endorsed by an institution.
When is an order marked as paid?
Only after the backend confirms a completed PayPal capture and validates the amount and currency. Reaching a payment return page alone does not complete an order.
Where are my downloads?
Confirmed purchases appear under My materials. A download is available only if the private file has been uploaded and Cloudflare R2 is configured for the deployment.
Can I download a preview before buying?
Preview files are not currently provided through the public catalog. The material detail page shows the information available for that listing.
How can I contact support?
Contact information is managed by the marketplace operator. Use the contact details supplied for the deployment or institution you are using.
