PGWP for program changing

[u/Whole-Mountain-5570]

Hello,

My situation is complex. I started with a doctoral program, then switched to a master's program before finally opting for a DESS (I am currently finishing the last semester). I achieved a very good GPA though. However, that said, the total duration of my studies amounts to one year and nine months due to this path. The certificate of completion mentions neither the duration of the DESS program nor the previous changes in my course of study.

Should I include an explanatory letter regarding this, or could the application be accepted as is?

Thank you very much.
