Best GATE DA Course 2027: The Ultimate Proven Guide to Crack the GATE Data Science Exam

What Is GATE DA? The GATE Data Science & AI Exam Explained

GATE DA (Data Science and Artificial Intelligence) is one of the newest GATE papers, first conducted in 2024 — and GATE 2027 is conducted by IIT Madras, with exams in February 2027. A strong DA score opens four doors: MTech/MS in Data Science, AI and ML at IITs, NITs and IISc; direct PhD admissions in AI/ML; PSU recruitment (BHEL, DRDO, ISRO and more); and GATE-based fellowships.

The paper is a 3-hour computer-based test: 65 questions, 100 marks (15 General Aptitude + 85 core), with MCQ, MSQ and NAT formats and negative marking on MCQs only. Full details in our GATE DA 2027 exam date, eligibility & pattern guide.

Why GATE Data Science Is the Career Move of the Decade

• Explosive demand: India will need over 11 million data professionals by 2026 (Analytics India Magazine, 2025).
• Gateway to top IIT MTech programs in DS/AI — among the most sought-after postgraduate seats in India.
• Research pathway with CSIR, DRDO and institute fellowships.
• Salary premium: MTech graduates from top institutes typically command a 40–60% premium over regular BTech placements.
