I'm not sure why you would say something like "nevertheless" in this sentence. The idea that you receive a satisfactory mark indicates that you will be satisfied. I would say, "I will pass with a satisfactory mark, so I will be satisfied with that." If, for some reason, a satisfactory mark is considered a bad mark, then I would say, "I will definitely pass with a satisfactory mark, but that mark, nevertheless, will be satisfying for me."

1. I will definitely pass with a satisfactory mark. Nevertheless, it will still be satisfying. 2. Though I will be getting a satisfactory mark, I will be satisfied nonetheless. 3. I will definitely be getting a satisfactory mark. However, I will be satisfied nevertheless.

Although I will pass with a satisfactory mark, I will be glad I did. Sorry I don't understand the nevertheless part
