It's a 2 year BTEC Course (yeah, laugh all you want people - but I'm clever enough to do Biology and Psychology as well) which basically looks at how the health sector does everything really. In year 12, you look at how Positive Environments are created etc, and then you look at effective communication in health care settings as well as how the law in health works and how it protects service users, then your examined on social aspects and lifestyle choices, as well as human growth and development.
In year 13 you take this further, investigating disease, and the effect this has on growth and development, creating your own health promotion, and then you look at the history of health and social, and back into the 1940's and the welfare state from when the beveridge report suggested NHS for all.
Then you can double it as well, by taking another 6 modules like I did =/
