General Studies and Engineering Aptitude
General Studies and Engineering Aptitude tests current issues, engineering ethics, governance, project management, ICT, environment and energy, and basic quantitative aptitude. ESE Prelims uses this paper to test judgment and awareness, not rote facts alone.
Core rules
- Engineering ethics: public safety, competence, honesty, confidentiality, conflict-of-interest disclosure and sustainable development. A licence to practise is a privilege with duties, not a commercial asset.
- Project management: CPM uses deterministic durations; PERT uses three-point estimates. Critical path is the longest path; float is slack.
- Environment: EIA, pollution control, renewable energy, energy efficiency and lifecycle thinking. Correlate causes with data before drawing conclusions.
- ICT: digital governance, cybersecurity, cloud, databases and e-services. Know basic terms rather than vendor claims.
- Aptitude: percentages, ratios, averages, data interpretation and logical reasoning.
Worked example
Activities A=2 days, B=4 days, and C=3 days; C starts only after both A and B finish. Earliest start of C is max(2,4)=4 days; project duration is 4+3=7 days. A has 2 days of float, while B and C are critical. The reasoning is to take the maximum of predecessor finish times.
Traps
Confusing correlation with causation in current-affairs passages; treating PERT as a fixed-duration method; choosing an ethically convenient answer over a safety-first answer; and ignoring the units in aptitude data. In governance questions, prefer transparency, accountability and due process.
