I guess each and every student has ever come across this basic stuff in his or her entire academic life. Critical essays are the most commonly tested form of academic evaluation techniques aimed at focusing on the research and knowledge capability of a certain discipline. It usually takes into account the analysis of books, films or even painting. The lecturer or the concerned individual tries to test the student on the explanation of some of the specific aspect from the book, painting or the movie where he or she expects an elaborate interpretation of the specific tested part. Furthermore, the lecturer might not only focus on this aspect alone but also might test one on the tonal variations of the whole segments.
