President Pranab Mukherjee signed an order allowing state boards to skip the uniform medical entrance examination, NEET , for a year.
NEET is the National Eligibility-cum-Entrance Test for admission to medical colleges.
Ordinance cleared by the Cabinet on Friday, is aimed at "partially" overturning a Supreme Court order.
Apex court ruled last month that NEET would be the only test for admission to medical courses in India. It turned down an appeal by several states who wanted to hold their own separate medical entrance exams.The top court order said all government colleges, deemed universities and private medical colleges would have to use NEET's results and not their own entrance exam results for admission.
The ordinance was sent to the President last Saturday after which he had asked the health ministry to explain the reason for taking an ordinance route to keep state boards out of the ambit of NEET.
Health minister JP Nadda then president on Monday to answer his questions on the need for urgency in issuing the executive order.
Around 6.5 lakh students have taken first phase of NEET held on May 1. The next phase of the exam is scheduled for July 24.
