About Plagiarizm in GRE AWA

Hi There,

I have practised almost 1/3 of the ETS Issue prompts from their pool. Now, I
am afraid when taking the real test if the issue prompt is similar from those
already practised, my response might be red flagged as plagiarized as it may
be similar in content of the response I had already submitted on this

Is there a way to delete my submitted responses here?
