Preparation Strategy

Practice the Full Paper Under Time Pressure: Engineering Services Examination (IES/ESE) is a single 100-question paper in 120 minutes — work out your per-question time budget (roughly 1.2 minutes each) and stick to it in every mock attempt.
Prioritize the Syllabus by Weight: Focus first on Engineering Mathematics and Engineering Aptitude, then move to General Studies, Discipline Core Subjects — these are the subjects tested in the actual paper structure.
Respect the Negative Marking: A wrong answer costs 0.33 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.
Simulate the Real Timer: Take full-length 120-minute mock tests on YourMockTest under exam conditions before attempting the real Engineering Services Examination (IES/ESE) — pacing under pressure is a separate skill from knowing the syllabus.
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.
