Where can I go to get a basic level of knowledge on accounting, economics and statistics without taking actual classes? Are there any good sites or programs that have online modules to cover what would be in a typical entry level college class? I'm going into the WGU online MBA program but my liberal arts BA degree has given me no background or experience in those areas. And WGU has no preparatory program available for getting up to speed. I'm pretty sure I'm going to struggle unless I do something to fill in the gaps myself. Thanks for any recommendations you all may have!
