Help with school

does anyone know how to remove a document of a website

The question is quite vague. Can you give us more details of what you are attempting to do?

i want to remove a document I uploaded to my student profile, but I am not sure what parts to remove and to leav

Can you give even more details? Are we talking about freeCodeCamp for eg or some other website? What do you mean by document? (In the world today, the word document has many meanings)

I was supposed to upload a pdf of my final year result document but I uploaded jpg document of the same content now I want to remove it from my student profile and yes, it is on a different website

In this case you should contact the administrators of the website you uploaded your file to as they would know how to help you reupload
