Reasonablity of evaluation methods in developed countries for Maths and Sci students
Why do yo suppose that the deciding factor in how programs evaluate student is the economic development of the country? Unless you have evidence to suggest otherwise, I don't think it is reasonable to make sweeping generalizations and judgement about how science programs in developed and developing nations assess their students. Instead, whether a course emphasizes exams or not depends on the nature of the subject and the level of mastery the students possess. For example, for a calculus class, it is very likely that you will be graded on your ability to do computational problems in an exam setting, and few independent projects or presentations will be required. However, in a graduate level seminar course in biology, for example, your daily discussion participation in the class will be more important, because the professors are more interested in your ability to think rather than memorization.
