One of the main characteristics of any A-level course of study is that examiners demand that you, as a student, develop the ability to both understand and, most importantly, demonstrate two basic forms of knowledge:
Firstly, the ability to understand and demonstrate the difference between facts and opinions.
Sociologists, in basic terms, attempt to produce factual knowledge about human behaviour. We try, in short, to generate statements about the social world that are demonstrably true (that is, we are able to show, through the use of supporting evidence, that these statements are true).
In basic terms, therefore, factual questions relate to what we know about the social world. It is important to remember this idea, since it will form the basis for a great deal of your work during the course.
Secondly, the ability to understand and demonstrate how factual knowledge is created and, by extension, the significance of this knowledge in terms of social behaviour.
