As of now, the last date to apply for CLAT 2020 is July 1st. And we still have few more days to go. And according to an official notice dated May 18th available at https://consortiumofnlus.ac.in/documents/Notification-of-extension-CLAT-2020.pdf , the statement says that students will be given atleast 21 days prior notice for the exam schedule and this shall be announced atleast by July 1st which is the last day for registration. Now what needs to be considered here is CLAT UG eligibility is based on the marks secured in your 12th. The latest information that we have is that CBSE exams have been cancelled. The CBSE exams that have been scheduled for July 1st to 5th have been cancelled as per CBSE's decision. So NLUs have to decide the calculation of eligibility criteria. Once NLUs decide the exam date you will be able to download your admit card atleast 21 days before the exam is scheduled and then attend the exam. So there is nothing to be worried about because CLAT exam has not bee scheduled yet. Please do post your question sometime next week and hopefully we should have more information for you.
