in neet ug 2020 there is an option to edit documents so without nta's notification one can change documents as i can access that option without any notification by neet

Nisha, if NTA hasn't notified you to uplpad any images ot documents, then you are good. But if the Edit option is available and then you want to utilise the option touplpad any of the images you can do that. But what you need to remember is today is the last day of the correction window and NTA hasnt officially announced any extension. Which means in case, the uploaded images are not up to the mark, you might not have another chance at correction. So please think and take a decision.
