Why Indian History after 1947 is not part of the curriculum of school education in India?

Yes, Now I understand these are to be taught to the students because other wise they would end up making mistakes like you did (India fought china in 1962)

Because the Board of Education doesn't want followers of political parties pelting stones at their office.

Recently I read this book 'India After Gandhi' by R.Guha and I came across this statement - In the Indian academy the past is defined as a single, immovable date: 15 August 1947. Thus, when the clock struck midnight and India became independent, history ended, and political science and sociology began. There are various reasons for this question - People don't consider the era after 1947 as history rather all that has happened during the last 55 years may filter through them easily civics syllabus, popular cinema and television; history as formally constituted knowledge of the past does not cover it. By  training and temperament, historians have restricted themselves to the period before Independence. A vast literature grew – and is still growing – on the social, cultural, political and economic consequences of British colonialism. A even more vast literature grew – and it too is still growing – on the forms, functions, causes and consequences of the opposition to colonial rule. HISTORIANS HAVE GIVEN MORE ATTENTION THAN WHAT IS REQUIRED TO PRE 1947 ERA. History before 1947 had social reformer, spiritualist, prophet and political agitator Mohandas Karamchand Gandhi.That great institution, the British Raj, and that great individual, Mahatma Gandhi, continue to be of absorbing interest to historians. But the history of independent India has remained a field mostly untilled. If history is ‘formally constituted knowledge of the past’, then for the period since 1947 this knowledge practically does not exist The Republic of India is a union of twenty-eight states, some larger than France. Yet not even the bigger or more important of these states have had their histories written. In the 1950s and 60s India pioneered a new approach to foreign policy, and to economic policy and planning as well.There were many controversies whose proper explaination is still not known.Authoritative or even adequate accounts of these experiments remain to be written.
