The psychological studies show that if students whose abilities are below the average, spend on homework only 1-3 hours per week, their results are consistent with the results of average students who do not do their homework.
Nowadays tutors invent more and more different types of tasks and exams. Some of them are looking for unusual ways of education; others just follow their bright imagination. The truth is that not all of students are keen on doing their homework. During the semester the main aim of each student is to avoid doing extra tasks. Of course, students show enthusiasm while studying particular subjects, but it is impossible to be specialist in all areas of science. Anyway, tutors assign written tasks – it is their job. And students have to find the will to do everything.
