ACS MasterKey is a downloadable digital product, delivered instantly and watermarked to you the moment you buy. Because of that, all sales are final — we don't offer refunds for a change of mind, a duplicate purchase, or exam results. You acknowledge this at checkout before paying.
We stand behind the product working. If your copy won't open, or a hyperlink doesn't land where it should, email [email protected] with your order number and we'll fix it or re-send your copy — fast. We'd much rather get it working for you than leave you stuck.
It's a navigation aid over verbatim FAA references for the oral and practical exam — not for the closed-book knowledge (written) test. Your copy is licensed to you individually and may not be redistributed.
