At this point in time, NTA has reopened the correction window until May 3rd. It totally depends on the control of Corona Pandemic. As long as there is spread of this virus NTA will not conduct NEET. Because now it also has  been proven that this can be also transmitted through Community. At this point in time, we do not have a definite time frame but we have to wait until the current lock down period is completed. To help you with your NEET preparation, we have NEET Knockout packages that you can check at: https://learn.careers360.com/knockout-neet-may/.
