See till now, there are no such cases where due to covid the date of application is extended. So in general, the probability of happening so is very less and for covid upsurge, the date of the examination may get postponed but the extension of the application date have a very feeble probability.

Although, you didn't mentioned the name of the course you are talking about, I would recommend you to get back to career360 and repost the question so that we can confirm if there are any such extensions or you can keep an eye on the official website of the examination as well.

Have a great day!
