This book is fairly OK, as a basic book in Business Economics or Basic Accounting/Finance. But if this is the base of the Swedish Civilekonom education, it explains why todays Swedish leaders have a very narrow and simplistic view of the world. Thank God for the MBA education, that you may get outside of Sweden!
This is a book extremely focused on the number crunching aspects of business (and not very advanced number crunching). If that is your interest, be my guest. Otherwise, there are better books.
