Discrete Mathematics (DM) is one of the most important subjects in the GATE CSE exam because:
- It contributes approximately 7–9% of the total 100-mark paper.
- It consistently carries 7–9 marks across multiple years.
- Questions are generally concept-based and well-defined, making it a high-scoring section with proper practice.
The table below shows marks distribution and number of questions of Discrete Mathematics for the past five years:
| Year | Approx. Marks | Number of Questions | Difficulty Level |
|---|---|---|---|
| GATE 2025 | 6–8 marks | 3–4 | Moderate–Hard |
| GATE 2024 | 8 marks | 3–4 | Moderate |
| GATE 2023 | 7–8 marks | 3–4 | Moderate–Hard |
| GATE 2022 | 8 marks | 3–4 | Moderate |
| GATE 2021 | 7–8 marks | 3–4 | Moderate |

Topic-wise Questions From Previous Year GATE Exams
Questions from this section are usually well-defined and concept-based. It is easier to score full marks by practicing questions from PYQs and from important high-weightage topics such as Propositional and First-Order Logic, Set Theory & Algebra, Combinatorics etc. The links to quiz of these topics are given below:
- Propositional and First-Order Logic
- Set Theory & Algebra
- Partial order and Lattices
- Monoids and Groups
- Combinatorics
- Graph Theory
- Recurrence Relations
