[kidovna]

ok but. which board did you study in and on a scale of 1 to 10 how would you rate it

i studied in an IGCSE school till 4th std (rating 6/10. it’s fun when you’re a kid and it’s montessori based but thats it),

CBSE from 5th to 10th (rating 7.5/10 because i had moderate amounts of fun but 10th std math was my first experience with wanting to end it all),

and ISC for 11th and 12th (7/10 only because i took classes i like - political science, history, art and english.)

the only board i haven’t studied is state board and if i’d done that i’d be more proficient in reading/writing tamil. what was the point of studying sanskrit for 3 years.

When the BJP-led NDA came to power in 1998, the government of India's human resource development minister Dr. Murali Manohar Joshi included 'Priesthood and Ritualism' into school curriculum. During his time, astrology began to be taught instead of science-based astronomy. Learning how to perform the Putrakameshthi Yajna, a (Vedic) ritual to get a male child was also introduced. They are inculcating unfounded beliefs and foolishness into children's minds. Recalling Golwalkar's call for involvement in RSS activities to be essentially devoid of any critical thinking and discernment, once they are in power, they have set about implementing this in children's education. Recently, CBSE has removed several topics from their syllabus. Of these, topics such as democracy and diversity, impact of globalization on agriculture, popular (mass), movements and communalism were removed from the Class 10 syllabus. It is for this kind of school curriculum excisions that the RSS has nurtured one of its offsprings, the 'Shiksha Sanskriti Uttahn Nyas. It has consistently been pressurizing NCERT to remove from textbooks, allusions to 'the former prime minister Manmohan Singh's magnanimous apology for the Sikh riots', and the 'killing of around two thousand Muslims in the 2002 Gujarat riots'. This is their chicanery.
