Dear student,

You heard it right.

All the students will be graded on the basis of their percentage in either half yearly or prelim exams in Class 9 and 10.  The students who have secured more than 90% will be graded as A-1, those who have scored between 80% or more than 80% but less than 90% will be graded as A, less than 80% but more than or equal to 70% ones will get B grade and then on like this.

Now coming back to your main question, what if someone has less than 40% in their half yearly exam, then you must now that in this case they will be promoted/passed but on their marksheet, it will be written mass promotion. So yes, they will not fail the students.

But please note that this mass promotion rule is only for students of GSEB and not for the not for the odd external students.

I hope this information helps you.

All the very best!!
