The crucial standard X and XII examinations are set to start from Monday onwards.
According to the estimates, more than 28 lakh candidates would appear for these exams.
The exams are being conducted by the Central Board of Secondary Education.
It is said that a total of 16,38,428 candidates have registered for class X examination, while 11,86,306 candidates have registered for class XII examination.
The class X board examination has been reintroduced from this year.
This was done after the government decided to do away with the Comprehensive and Continuous Evaluation (CCE) adopted earlier.
The exam will be conducted at 4,453 centres across India and 78 centres outside India.
Similarly, for class XII, the exam will be held at 4,138 centres in India and 71 centres abroad.
