Here is your 10-point cheat sheet to this big story:
"The sensitive government has taken decision in the interest of students. No nationwide retest for 10th class mathematics paper barring Delhi... Haryana, that too, if needed," Education Minister Prakash Javadekar tweeted.
It has been decided not to hold the re-test at CBSE schools abroad because there is no information that they had access to leaked question papers, Mr Swarup said.
"You can always question a decision but we had to take the best possible decision, given the information that was available to us," he said, underlining that there are no perfect answers.
Mr Swarup said the government and the CBSE had taken different approaches to deal with reported leaks of the Class 10 Mathematics and Class 12 Economics paper. Since most Class 10 students continue in the same school, government sources explained, students would not lose their competitive edge to students who may have had access to the leaked papers.
This isn't the case for Class 12 students where admissions to colleges would not only be determined on the basis of marks scored by them, but other students as well. The nationwide re-test for the economics paper is aimed at ensuring that students who had access to the leaked papers do not have an advantage in college admissions.
Mr Swarup said the decision to hold the Class 10 Mathematics paper in July would ensure that the schedule of the students and their parents was not impacted. It also works well with the CBSE which holds compartment examinations, for students who fail in one subject, around the same time.
The paper leak has triggered massive outrage from parents and students against the CBSE, particularly its chief Anita Karwal. To demands that she be sacked, Mr Swarup said "you cannot hold someone responsible without an investigation". "Let there be a clear inquiry and action will be taken against whoever will be at fault," he promised.
He also addressed the criticism that the CBSE had acted too late despite having been tipped off about the leak. Since the email about the leaked paper was sent on her official email, she saw it only minutes before the examination was to start. By the time she got a confirmation that this leak was for real, the examination had already started.
"Our immediate concern is that the children of this country should not suffer unnecessarily. The decision we have taken is in their interest but this does not mean the inquiry will end," Mr Swarup added.
"PM wrote Exam Warriors, a book to teach students stress relief during exams. Next up: Exam Warriors 2, a book to teach students & parents stress relief, once their lives are destroyed due to leaked exam papers," Congress president Rahul Gandhi tweeted.
