PSLE Science case studies

PSLE Science · Put your knowledge to work in context.

The Primary School Leaving Examination (PSLE) is an annual national examination taken by candidates at the end of their final year of primary school education in Singapore, as described by the Singapore Examinations and Assessment Board (SEAB). It is therefore intended for primary school pupils finishing their final year, and it functions as a national checkpoint at the close of primary schooling rather than an optional or professional certification. SEAB's PSLE pages group the practical information candidates need into a few areas: important dates for candidates, the formats examined, the rules and regulations for candidates, exam arrangements during a haze situation, train disruption advice, access arrangements, e-exam resources for school candidates, an exam readiness checklist, approved calculator and dictionary lists, distributors of past years' papers, and results slips and certificates. SEAB also publishes an examination calendar and a section explaining key exam processes behind the scenes. The PSLE Science case studies are 5 cases and about 1,584 words.
