I am not happy with my master thesis grade. I wrote down my master thesis in a company. I had three supervisors in this 6 month period, two of them from university and one of them from the company. I worked three days of the week in the company (my task is implementing of an app) and other days I focused on my report. I made all the corrections in the report that my supervisors offered and went to the meetings regularly. I feel really disappointed to grade (2.7); I expected to get 2.0.
How should I explain my ideas to the assistants and what should be the first step? On the other hand, I am really angry and I could not even thinking about the subject in a healthy way. I need to some professional ideas or someone who had the same experience before.
Edit: The company found this chair to me and they have still contact and they are making projects in cooperation. I saw my grade in online system, I have not yet got my diploma.
Edit: The sign of the good work (I presented my work also in the company after making the presentation in university and they liked the results.) Also some of the colloquies of the company think as same as me that I deserve better than 2.7.
