Students offering H2 Science subjects from 2016 onwards will sit for the Science Practical Exam (Paper 4), which replaces SPA (School-based Practical Assessment).  Paper 4 is designed to assess students’ competency in practical skills which can be realistically assessed within the context of a formal practical assessment. Students are assessed in the following skill areas: planning (P), manipulation, measurement and observation (MMO), presentation of data and observations (PDO) and analysis, conclusions and evaluation (ACE).
