GATE CSE 2027 Exam Pattern follows a structured 100-mark format designed to test comprehensive understanding across 65 questions, with the examination tentatively scheduled for February 2027. The paper is divided into three main sections: General Aptitude (15 marks), Engineering Mathematics (13 marks), and Core Computer Science subjects (72 marks). Candidates will face a mix of Multiple Choice Questions (MCQ), Multiple Select Questions (MSQ), and Numerical Answer Type (NAT) questions within a 3-hour duration. High-weightage subjects like Algorithms, Programming & Data Structures, and Operating Systems typically carry 10–15 marks each, making them critical for a top rank. Success in GATE 2027 requires mastering the marking scheme, where MCQs carry a 1/3 or 2/3 negative marking penalty, while MSQ and NAT questions offer a safety net with no marks deducted for incorrect answers.
