Is a N award in school certificate good thing because you got one?

Whether a "N" award in a school certificate is a "good thing" depends entirely on the context. "N" could represent many different things. It's not a standard grade across all school systems.

To determine if it's positive, you need to know:

* What does "N" stand for? Is it a passing grade? A failing grade? Something else entirely (like "Not Applicable," "Needs Improvement," or a specific numerical value within a grading system)?

* What is the grading scale? Is it a letter grade system (A-F), a numerical system (1-100), or something else?

* What are the expectations? Is getting an "N" considered average, below average, or exceptional?

Without this information, it's impossible to say if it's good or bad.
