I would like to start learning about business and I'm thinking of taking a course next year that focus's on these points specifically

*understanding of the financial statements of a company
*commercial law, particularly the law of contract
*contemporary economic principles and theories
*roles and responsibilities of management
*marketing principles
*business communications
*Learn how to analyse financial statistical data

I don't really know anything about business/economics/marketing could someone give me a good place to start perhaps a book or a website one that focuses on the same points would be much appreciated.
