3) Learning by heart is pointless if a student just memorises textbooks without truly understanding the concepts inside it and the meanings behind it, students cannot answer questions which are seldom asked in several ways as they are used to memorising answers to questions that they had only memorised. By just plainly memorising students are limiting their  ability to think flexibly. Students might also lose or might not give the chance for developing creative thinking which helps in the development of the society and thus the country. However, it is not totally pointless because in the end a student still has to memorise what they had learnt with understanding.
