Internal control principles Book

Well,,,this book was a nightmare to me as a student,,
it's too heavy so i didnt bring it on every intermediate accounting class which was for a year,,
but..after a year or so..now i realize that this book teach me so much than i thought back then,,
this is a must have book for any accounting students who works in any accounting-involved work..
even though they will publish a newer edition but at least you have to have one.
