Exam is the test of brainpage achievement in which grade quality is awarded for academic performance.
Advancement of science and technology is the result of human learnography. Education gives teaching while smart brainpage develops from learnography to drive problem based learning.
Learning brain doesn’t support teaching as it can’t modulate brainpage for learning. Teachers are blamed for low performance but there is a bug in education system.
Primary learning of brain is first degree of learnography and children possess this aptitude by birth. Learning of higher degree is acquired by knowledge proficiency and skill development.
Phases of learning are not teaching system but based on brain learnography defining the science of learning mechanism and brainpage development in school system.
