"If things go wrong, don’t go with them"
Students were graded not just on their academic performance but also grades were given for their extracurricular activity like public speaking, artistic skills, sports among many other factors. So their grades were just not based on academic performance.
Since that was the first year there were many training programs for the teachers as well. Since they had to grade the students, they were in as much dilemma as the students because for ages the traditional method was followed and suddenly this came into effect. Along with the students, even the teachers had to do their homework properly. That year equal importance was given to other activities apart from the academic work, though it gave a rose to many criticisms.
I am unsure how it is now in the CBSE schools.
