1. Understand the Exam Pattern
Duration: 2 hours (online)
Questions: ~100 MCQs
Negative Marking: Yes (1 mark deduction for wrong answers)
Subjects: Based on your engineering/science discipline (no general aptitude)
2. Focus on Core Subjects (GATE-Level)
BARC paper is similar to GATE but often more conceptually tricky and calculation-intensive.
For Engineers (e.g., ME, EE, ECE, CSE):
Focus on core subjects—Strength of Materials, Thermodynamics, Signals, Control Systems, etc.
Avoid too much theory. Focus on numerical problem-solving.
For Science Streams (e.g., Physics, Chemistry):
Master concepts from MSc level textbooks (like Griffiths for Physics, Atkins for Chemistry).
3. Use GATE Materials but Practice BARC-Style
Use GATE books and coaching notes for concepts (e.g., Made Easy, Ace Academy).
Solve GATE previous year questions.
Then practice BARC-specific MCQs, which are shorter, faster, and calculation-based.
4. BARC Is Speed-Driven – Practice Fast Calculations
Unlike GATE, BARC does not allow calculators.
Improve mental math, unit conversions, and estimation skills.
Solve 100+ MCQs in 2 hours = ~1.2 minutes per question.
5. Revise Smartly
Make short notes or formula sheets for last-minute revision.
Revise daily or weekly, especially weak topics.
Focus on conceptual clarity, not just memorization.
6. Mock Tests & Previous Papers
Attempt BARC mock tests under timed conditions.
Use portals like Gradeup, Testbook, or self-timed mocks.
Analyze your mistakes and build a topic-wise improvement list.
7. Prepare for the Interview (If Shortlisted)
BARC interviews are oral, technical, and deep.
They ask fundamental questions (not just definitions).
Be ready to derive, explain, and draw on the board.
Pick 2–3 strong subjects and prepare them deeply.
