Frequently asked questions
How much do the sciences PDFs cost?
Every PDF on the site is $14.99. One file, lifetime access, no subscription.
How do I get my PDF after buying?
Instantly — a download link appears on screen and lands in your inbox the moment your payment clears. One file, lifetime access, no subscription. Every purchase is backed by a 14-day money-back guarantee.
Will this match my exact edition?
Each PDF is built around a specific edition. If your professor assigned a different edition, the chapter numbering may shift slightly — the topics and objectives are usually unchanged from edition to edition.
How are these different from a test bank?
Test banks reproduce instructor questions copied from a textbook — that's a copyright problem. We write fully original chapter summaries and exam-style questions from scratch.
Can I request a textbook?
Yes. Drop us a note via the Contact page with the textbook title, author, and edition and we'll prioritize requested books.
