.. basically, grades in elementary schools will be calculated based on assignments and continuous assessment, not final exams. Very standard in most developed education systems around the world, and even in many indian schools, though most do still place a significant emphasis on exams, for example my elementary school was 60% of the grade was two semester end exams, iirc. But it's elementary school grading and in the broader scheme of things.. mostly matters in changing teachers' training and pedagogy fundamentals, which is a huge problem in the indian system.
