- Subject Assessment Guidelines for Life Sciences
The Life Sciences MasterClass Series of videos was produced to highlight, clarify and refine the most important content and concepts as described in the Subject Assessment Guidelines (SAGs) for Life Sciences.
In these videos, the content has been summarised in an easy-to-understand and accessible way. Real life examples are given in order to contextualise the Life Sciences content; the concepts with which students struggle regularly are explained in a step-by-step manner. This helps the students when they need to apply their knowledge in unfamiliar contexts.
Skills such as writing biological essays, practical skills and exam answering techniques are addressed. The student is given tools in order to tackle these often daunting applications of Life Sciences, giving them the confidence when writing exams.
These classes can be used both to learn content the student doesn’t understand as well as to revise before writing exams.
