I am a 5th year Ph.D. student in Computer Science. My advisor thinks that I have made a good progress during my Ph.D. and I should give my Ph.D. synopsis presentation. In the Ph.D. synopsis presentation, the student briefly presents the work to the research committee so that they give approval of writing the doctoral thesis or any final feedback. If done, it means the Ph.D. is almost completed.
However, I think that I have made good progress but not to a level that I expected. I do not have quality publications yet. I have 2 tier B papers, 1 tier A paper, and 2 papers (average ones) currently under submission. How should I communicate to my supervisor that my Ph.D. might not be a good Ph.D.? Also, should I even communicate this issue to him or not?
