I am doing a master's study in a German university. I had some setbacks during my master thesis project's lab work. This delayed the time I had available to write my report later on. The setbacks were not enough for an extension of my project by the examination office (My school has very strict rules for extension). So by the time the official deadline for submission came, I submitted a written report that was not very good quality (not so bad that I would fail, but not so good that I get a good grade either).
However, my supervisor knows the setbacks I had and the commitment and hard work I had shown to overcome them, so he agreed to give me an extra week to work on my thesis report and he will grade that instead (instead of the submitted report).
My questions are:
The extra time would allow me to do a much better work than the officially submitted report. What happens when somebody compares the quality of my officially submitted work and a grade that doesn't match with it (maybe better grade than the report deserves?)?
The official and more permanent record of my thesis would be a sub-standard report that does not reflect the time and effort I spent in the practical work. Is there possible way to fix this?
Is this considered an academic misconduct?
Thank you in advance for your insight.
