TIFR GS Mock Test 2026

Part A Common · Part B Computer Science. Negative marking: 1 per wrong answer. The official paper is 45 questions in 180 minutes with no per-part time limits and free navigation. This mock covers the 30 questions that count for Computer Science admission, on a proportional 120-minute TakeMockTest timer rather than an official sectional limit..

For Computer Science admission, TIFR counts Part A and Part B and ignores Part C, so Part C (Learning, Information and Data Science) is not covered here. Questions carry five options, which is the official width for this paper. Part B follows the published Computer Science syllabus: discrete mathematics, formal languages and computability, data structures and algorithms, programming languages and compilers, operating systems and concurrency, switching theory and digital circuits, and theory of databases. TIFR identifies Part A as common but does not publish a separate formal Part A syllabus, so the Part A questions here use broad mathematical and logical common-test reasoning rather than claiming a syllabus that does not exist.
