Hi cbsc management & all,
After finishing 2017 10th grade exam, most of the students in gulf region was crying and saying they will not get good marks. But result was unexpectfull result.in this 2017, gulf region is blessed with a+ by cbsc. What is the secret of these a+.
Cbsc is kindly requested to do the revaluation of 2017 10th grade exam papers properly. Because cbsc given high marks to some students like offer we get in supermarket. This is unfair.
