Smart study helps students build motivation and uplift their moods.  Studying important portions makes them feel comfortable about the topic they need to study for their exams. They get familiar with the chapter and obtain the confidence to deal with other theoretical aspects and solve numerical problems. The smart study is one of the finest ways to gain motivation. Students should start with selective study to cover the entire topic in the first place. Once they gain confidence, they can increase the depth of covering the chapter.
