DSTA Entrance Examination case studies
DSTA Entrance Examination · Put your knowledge to work in context.
The DSTA Entrance Examination is the selection test used by Singapore's Defence Science and Technology Agency (DSTA) to assess candidates applying for internships, scholarships and graduate roles in defence engineering and technology. It is a broad aptitude screen rather than a test of engineering knowledge: it probes how quickly and accurately you reason with words, numbers, abstract patterns, mechanical and spatial relationships, and data, plus how you judge workplace situations. The DSTA Entrance Examination case studies are 5 cases and about 2,816 words.
