My husband got his thesis back. He had submitted it for review. After two or three times of he submitting and his adviser wanting him to make changes, the pages are filled with notes from "repetitive" to "awkward wording" to "move this to ..." or "this doesn't make sense here, move it to...".
He has 3 days to finish it. He will be able to make some of the changes. But English will NEVER be his first language. There will always be "awkward words".
