How each page works

Built for fast revision

  • Quick Recall boxes: the facts to hold in memory
  • Formula boxes with variables, when each applies and the usual mistake
  • Students Think / Actually: the wrong intuition next to the correct rule
  • If You See This / Do This: a cue in the question and the steps to take
  • Compare tables for look-alike concepts
  • Trap boxes: a known wrong turn and its fix
  • Edge cases that change the answer
  • Decision flows to run in order
  • Master tables for quick lookup
  • Worked mini-examples
  • Diagrams

About this pack

Scope

Revision pages for Section 1 of the GATE CS 2027 syllabus. Discrete mathematics takes the first half: propositional and first-order logic, sets, relations and functions, posets, lattices and groups, graph theory bounds, colouring and matching, combinatorics and recurrences. The second half covers rank and linear systems, eigenvalues and LU decomposition, limits, derivatives and integrals, Bayes' theorem, random variables, distributions and descriptive statistics. Theorems are stated with the conditions under which they hold, and solved past questions are cited by year, set and question number.

Before you buy

Common questions

What exactly will I receive?

A 14-page A4 PDF in two editions: a screen edition for reading on a device and a print edition prepared for A4 printing. Nothing is shipped; it is a download.

Can I read it on my phone, and can I print it?

Yes. The PDF opens in any PDF reader on phones, tablets and computers, and the bookmarks jump between pages. You may print it for your own study.

Is it for GATE 2027?

Yes. The packs follow the official GATE CS 2027 syllabus, and each pack says what is in scope and what is covered in another pack. GATE CS Mastery is independent and not affiliated with IIT, IISc or the GATE organising committee.

How is this different from ordinary short notes?

Each page answers one question and uses labelled boxes: rules with their conditions, traps with the fix, comparison tables and small worked examples. Every pack ends with a traps sheet, a question-patterns sheet and a one-page last-day sheet.

What happens after I pay?

When Razorpay confirms the payment, download buttons appear straight away and a receipt is emailed to you. Later, My library sends a one-time link to your purchase email and shows fresh download links.

What if the payment succeeds but the download fails?

Do not pay again. Your purchase is recorded as soon as the payment is verified. Open My library, or write to support@gatecsmastery.com with your order ID or Razorpay payment ID. See the refund policy for when a refund applies.
