Any student who has secured between 91 and 100 in a subject, has an A1 and a grade point of 10. Thereby any student who has scored more than 91 in every subject has a grade point of 10 and hence qualifies to be labelled among CBSE Class 10th toppers.
Scores between 81-90 fetch an A2 grade or 9 points; 71-80, B1 or 8 points; 61-70, B2 or 7 points; 51-60, C1 or 6 points; 41-50, C2 or 5 points and 33-40, D or 4 points. D is the qualifying grade, and those scoring between 21-32 E1 and 20 and below-E2 will be required to improve their performance.
SBOA school has 142 ten-pointers out of 687 students who appeared for Class X exams and DAV Gopalapuram, produced over 100 ten-pointers. Not just these, there are many schools across the nation that have a huge number of ten pointers and it is hard to figure out the actual CBSE Class 10th toppers this time.
