Preparation Strategy

1. Map Every Section to Time: OSSC CHSL splits 150 questions across 1 section in 120 minutes — decide a per-section time budget before test day so no single section eats your buffer.
2. Prioritize the Syllabus by Weight: Focus first on Current Affairs and Monthly CA, then move to Topic Wise CA, Arithmetic, Data Interpretation, Logical Reasoning, Computer/Internet Awareness, FTs — these are the subjects tested in the actual paper structure.
3. Respect the Negative Marking: A wrong answer costs 0 mark(s), so only attempt a question when you can eliminate at least two options — guessing blind against this penalty is a net loss over a full paper.
4. Simulate the Real Timer: Take full-length 120-minute mock tests on YourMockTest under exam conditions before attempting the real OSSC CHSL — pacing under pressure is a separate skill from knowing the syllabus.
5. Review Every Mistake: After each mock, spend more time reviewing wrong answers than attempting new questions — a repeated mistake in practice is a guaranteed mistake in the real exam.
