Unless your friend's thesis is super good and rated as an excellent graduation thesis, it will be easily found. ..

Personally, I don't think the graduation thesis will be carefully checked, but there are many accidents. If you don't have time to write, try to change it, change the topic, and then change a few words in a paragraph!

I'm writing a paper, too. I wrote it myself. I am not an experienced person. My opinion is for reference only ~
