New Delhi, Sep 7 - There would be no Class 10 public exams for Central Board of Secondary Education (CBSE) affiliated schools from 2011 and a grading system would be introduced from the current academic session, Human Resource Development (HRD) Minister Kapil Sibal announced Monday.

The minister told reporters here that board exams would be held as usual this academic year, but a grading system would be introduced along with the prevalent marks system.
