DISCLAIMER:
These videos are a revision guide designed to help students understand the requirements of the GCSE Science course, specifically the course specification(s) mentioned above. Although I say I can “help” students achieve a C grade, this should in no way be interpreted as a binding promise that this will definitely be a student’s final grade. I offer expert guidance to try to improve a student’s chances, but as there are so many factors beyond my control, I am unable to make any guarantee about the content of any exams or controlled assessments beyond any restatements of the relevant section or sections of the course specification(s). In my experience, a student’s final grade is mainly dependent upon the quantity and quality of preparation he or she puts in. All I can do is try to optimise this preparation. In short, no-one can guarantee a grade; I’m just here to help.
