Preparation Strategy

1. Map Every Section to Time: ISRO Scientist CE splits 20 questions across 1 section in 25 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 Core Engineering Discipline & Technical Subjects and Engineering Mathematics & Applied Science, then move to General Intelligence & Reasoning, General Awareness & Technical Aptitude — 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 25-minute mock tests on YourMockTest under exam conditions before attempting the real ISRO Scientist CE — 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.
