Class XII annual examinations, for which 10,98,420 students are expected to appear, would go on till April 29.
According to a statement released by the CBSE, the annual examinations of class X and XII will be conducted from March 9 in view of the state assembly elections being conducted in Punjab, Goa, Manipur, Uttarakhand and Uttar Pradesh.
The board has given careful consideration to the situation before postponing the exams by a week which will now allow the students to get more time for preparation and ensure uninterrupted sequence of examinations, the CBSE statement said.
The CBSE also said it has made all possible efforts to maintain reasonable time gap between the major papers and ensure that the students appearing for Joint Engineering Exam and upcoming National Eligibility cum Entrance Test complete the CBSE examinations ahead of these entrance exams.
The annual exam result will be declared on time as the board has adopted several IT initiatives which will aid in faster result processing, it said.
