Talk:A-level Economics

Could someone define what "A-level economics" is, and what AQA and OCR stand for?

After a quick google, "A-level" refers to a type of advanced high school curriculum. Could someone defend the existence of a 'principles of' and an 'a-level' book? The content should be identical. An 'A-level' reader/syllabus could be attached to the 'principles of' book instead. Jcress410 (discuss • contribs) 01:12, 6 April 2011 (UTC)
