Discrete Mathematics
Why this subject matters: Discrete math is the backbone of algorithm analysis, graph theory, and logic — subjects that show up both in GATE and in every serious coding interview involving proofs of correctness or complexity.
Standard reference
Discrete Mathematics and Its Applications
The most syllabus-aligned discrete math textbook for GATE CSE — comprehensive coverage of logic, set theory, combinatorics, and graph theory.
In-depth
Discrete Mathematics with Applications
Slower-paced and more explanatory than Rosen — an excellent first read if proofs and formal logic feel unfamiliar.
Practice & problems
Schaum's Outline of Discrete Mathematics
A large solved-problem bank matching the GATE-style question format closely.
