The document discusses proposals to introduce open book exams for classes 9-12 in CBSE schools in India. Open book exams allow students to bring textbooks into exams and focus on testing understanding rather than direct factual recall. The proposed changes aim to encourage students to learn how to quickly find information, understand it, apply their knowledge and develop critical thinking skills. Specific exam formats are suggested for some subjects in classes 9-11, with full implementation intended to be announced by the end of 2013.
