This is one of my reference book for this semester.
Mine is on the left hand side.
The original copy is on the right hand side.
My friend bought the book during her undergrad study from her lecturer. It only cost her RM59. At first, I want to purchase this book from the bookstore but it would cost me RM259.00. Furthermore, I have to wait for almost 1 month for the book because the bookstore has to order it from the distributer. So I just photostat it and it only cost me RM 25.20.
