When to include degree classifications on a CV
I would mention it and leave it on your CV going forward. It is recognized and awarded by your university. Some people might discount it and others might not.
It is a minor thing, however, as it is normally simply a reflection of your GPA. And in applications that contain the GPA, that is a more precise indicator of where you wound up.
But it is an accomplishment, nevertheless and it is valid to be proud of it.
