When it comes to new changes in GATE 2026, the exam expanded its academic reach by introducing two new subjects, Geomatics Engineering and Naval Architecture & Marine Engineering, reflecting growth in interdisciplinary and industry-relevant areas. This new change has expanded the total papers to 30, with a notable addition being the Data Science and Artificial Intelligence (DA) paper. Geomatics Engineering focuses on surveying, mapping, and spatial data technologies, while Naval Architecture and Marine Engineering covers ship design and marine systems. The GATE 2026 syllabus for all subjects still includes General Aptitude and Engineering Mathematics (where applicable), along with detailed core topics tailored to each new and existing discipline.

How to Prepare for New GATE 2026 Subjects?
Since your preparation plan may be tailored to pre-existing subjects in GATE, you may check the preparation tips for new subjects in GATE 2026 below:
Preparation Stage | What to Do | How to Do It Effectively | Applicable New Papers |
|---|---|---|---|
1. Understand the Syllabus Thoroughly | Analyze official syllabus line by line | Download syllabus, highlight topics, note overlaps with existing subjects | ES, DA, XH, EY, XE sections |
2. Identify Overlapping Subjects | Map topics to traditional GATE subjects | Example: ES ↔ Civil/CH, DA ↔ CS/Math, XH ↔ GA | ES, DA, XH |
3. Start with Fundamentals | Strengthen basic concepts first | Use undergraduate-level textbooks or NPTEL notes | All new subjects |
4. Use Standard Reference Books Only | Avoid too many sources | Pick 1–2 standard books per subject | All |
5. Leverage Previous Year Questions (PYQs) | Analyze available PYQs (even if limited) | Use last 2–3 years’ questions + similar subject PYQs | DA, ES, XH |
6. Focus on Conceptual Clarity | Prioritize “why” over “what” | Study derivations, logic, assumptions | New subjects mostly conceptual |
7. Build Short Notes Early | Create concise revision notes | One notebook per subject | All |
8. Use Interdisciplinary Learning | Combine knowledge from multiple domains | Example: DA uses Math + CS + Stats | DA, XE, IN |
9. Practice Numerical + MCQs | Solve mixed question types | Balance conceptual MCQs and NATs | ES, DA |
10. Track Weak Areas | Maintain an error log | Note repeated mistakes and misconceptions | All |
11. Attempt Subject-wise Mock Tests | Take new-paper-specific mocks | Start with sectional tests | DA, ES, XH |
12. Compare with Older Subjects | Study how similar topics were asked earlier | Example: Environmental questions in CE | ES |
13. Revise Frequently | Follow spaced repetition | Day 1, 7, 15, 30 | All |
14. Don’t Ignore GA | Prepare GA alongside new subject | GA overlaps heavily with XH | XH, all papers |
15. Focus on Accuracy | Avoid blind guessing | Attempt only sure questions | All |
16. Use Online Lectures Wisely | Prefer syllabus-aligned content | Use NPTEL / university lectures | All |
17. Create Topic-wise Checklists | Ensure full coverage | Tick topics after mastery | All |
18. Practice Integration Questions | Solve multi-topic problems | Common in interdisciplinary papers | DA, XE |
