I strongly believe that every student should work hard to obtain grades that truly reflect their potential. Everybody is different and special in their own way and everyone has their own potential. This also means that students will only be efficient in using their time and achieving their potential if they develop a reading/studying approach that suits them for each course/subject or even topic.
One way of doing this is by changing the point of view, that is, using a new/different approach that fits well with that particular student.
Efficiency will help students free up time for more review, extracurricular activities and also helping their parents at home or younger siblings.
