You need to upload scanned copies and not xerox copies. If you have uploaded the documents once, you cannot submit them again. But because you will submit original documents for document verification, you should be fine and there should be no issue. But if you are worried, please mail the helpdesk at: tspgecetadmqueries2020@gmail.com to ask them if xerox copies are acceptable or if there is another feasibility of uploading original documents. But because there is no correction window, you cannot make changes to the uploaded documents.
