Preparation Strategy for GATE 2026 Data Science & AI
Cracking GATE requires more than just studying—it requires a smart, disciplined approach. Here’s a step-by-step plan:
1. Understand the Syllabus Thoroughly
Go through the official syllabus and identify your strengths and weaknesses. For instance, if you’re comfortable with programming but less confident in engineering mathematics, allocate more time accordingly.
2. Build Conceptual Clarity
Rather than rote learning, focus on understanding the “why” behind concepts. For example, don’t just memorize SQL queries—understand normalization and indexing principles.
3. Practice Extensively
Since GATE is application-based, practice is the key. Attempt topic-wise problems and gradually move to full-length tests.
4. Analyze Previous Year Papers
Solving past year papers provides insights into exam trends and helps you manage time better. Pay attention to frequently repeated concepts and the level of difficulty.
5. Mock Tests & Self-Evaluation
Attempt timed mock tests to simulate real exam pressure. Analyze errors after each test and refine your preparation strategy.
6. Revise Regularly
Make concise notes for each subject. In the last 30 days, revision has become crucial. Focus on formulae, shortcut tricks, and important problem-solving techniques.
