Download official notification: Check eligibility, exam pattern, and discipline‑wise syllabus for the year.
Strong fundamentals: For Scientific Officer, deepen core subject understanding of your engineering/science discipline.
Focus on problem‑solving: The online exam emphasises application and problem solving rather than rote memory. barc.gov.in
Mock tests under exam conditions: Solve 100‑question sets in 120 minutes (for Scientific Officer) to build speed & accuracy.
Manage negative marking: Since each wrong answer reduces one mark, avoid careless mistakes.
Trade‑specific preparation for technician roles: Focus on trade topics, hands‑on skills and domain‑knowledge.
Revision notes: Maintain summary sheets of formulae, methods, short‑cuts and trade procedures (for technician).
Interview readiness (Scientific Officer): Be prepared to discuss academic projects, your discipline, and recent scientific/technical developments in BARC/atomic energy sector.
Schedule & consistency: Allocate daily study hours, rotate between core subject, past‑year questions, and mock tests.
Stay updated: Keep an eye on official site of BARC for announcements and changes in pattern or syllabus.
