Unit 1: Principles and Applications of science is an externally assessed unit in the form of a written examination (2 hours).  This is split into three timed sessions of 40 minutes for each science.


All other units are assessed internally and students will complete a series of assignments in a variety of different formats.


Each unit within the qualification has specified assessment and grading criteria which are to be used for grading purposes. A summative unit grade can be awarded at Pass (E grade), Merit (C grade) or Distinction (A grade).  Any single referred assignment will result in failure of the qualification.


The Future

Students who study this will develop the transferable and higher order skills which are valued by higher education providers and employers.  This includes, problem solving, working collaboratively, resilience, effective writing, reading scientific texts, practical and analytical skills.
