What you are asking is the thesis that is urgently needed for the graduation of a senior doctor. Should I hand it in? Shouldn't have handed it in. Senior students and younger brothers are in urgent need of papers for doctoral graduation, which shows that senior students and younger brothers can naturally realize that they are doctoral students and are in the stage of doctoral graduation. Therefore, seniors should have known for a long time that they need to prepare their graduation thesis in advance before studying for a doctorate, but now they are in urgent need of a thesis, which shows that they are not fully aware and prepared. But you shouldn't hand in your thesis either, because you also need a lot of papers to complete your studies. The creation and conception of a doctoral thesis are not simple. So you shouldn't give it to your brother.
