I am about to finish my masters degree, and I want to apply for a PhD in the near future. I know that when contacting a potential advisor, they will ask you to send your CV and your previous research. The issue is that, according to my current advisor, my masters thesis will have no issues on being approved and my grades are good. Due to the pandemic, though, I was not able to be in the country my university is located in; communication and feedback with my advisor was very complicated. In my opinion, my thesis could be improved in some ways, but now I am lacking the time to do so.
My question is: When a potential advisor asks me for my masters thesis or my previous research, it is compulsory to send the document I submitted for graduation? Can I send an updated version of it (I know I will be able to improve it, because I will work on it at my job)? Is this wrong?
