Practical details about choosing a book and accessing your purchase.
What does each book cover?
Use the description, table of contents and available sample on each book page to assess its scope. A book may focus on one part of the syllabus; we do not claim that every volume covers the whole examination.
Is this an official GATE publication?
No. GATE CS Mastery is an independent publishing project and is not affiliated with IIT Madras, any other IIT, IISc or the GATE organizing committee. Refer to the official examination website for authoritative syllabus information.
Do I need an account?
No. Checkout requires your name, purchase email and email confirmation. Payment is handled by Razorpay. Keep your order identifier after checkout.
How is a book delivered?
Published books are digital PDFs for personal study. After the server verifies a captured payment, a download link becomes available. An order confirmation is also queued for email delivery.
Why does the PDF contain an order identifier?
The footer identifies the licensed purchase without repeating your name or email on each page. This is a traceable personal-use license, not a promise that copying is technically impossible.
What if I lose my download link?
Request a one-time email link on My library using the address from your purchase. Links expire and have download limits; library access can issue a fresh link for an active purchase.
What if payment succeeds but delivery fails?
Do not pay again. Check My library, keep your order identifier and contact support. A delivery failure does not remove a successfully recorded purchase.
