Course at a glance

The Accredited Level 2 Diploma in Biology is designed to facilitate development of a broad understanding of biological principles and concepts and also includes relevant biological investigative skill development. Students will also learn how to evaluate the positive and negative aspects of scientific developments and advances.

The course is designed to be accessible for those with limited scientific backgrounds, and as such is an excellent starting point for students wishing to learn more about biological science.

The Accredited Level 2 Diploma in Biology course includes aspects of science that are relevant to everyday life and therefore appropriate for distance and adult learning. There is no practical coursework associated with the course but science skills and knowledge are integral elements of the core topics, so embedded within the course syllabus are independent learning activities and evaluation of practical based components to further assist students understanding of the subject.

The course is a year in length and divided into 2 units of study. At the end of each unit there is an associated TMA (Tutor Marked Assessment) which students are required to complete and submit. The course is formally assessed by an average grade being attained from the 2 submitted Assessments.
