Yes. The scores aren't bad so much as they're not particularly good. They're barely skating by with those scores, but a 2.0 will still let you graduate at most colleges.

GPA stands for Grade Point Average. Assignments that score 90–100% get an A. 80–89% are Bs. 70–79% are Cs. 60–69% are Ds. Everything below that is an F. Don't ask me what happened to E. I don't know that's just how it is.

Your GPA is a reflection of your average scores for all your assignments. Usually people mean GPA to refer to their cumulative GPA from all of their classes, not just one. A 4.0 GPA means you average an A on every assignment. 3.0 means you average Bs. 2.0 means you average Cs. 1.0 means you average Ds. 0.0 means you average Fs. So a 3.8 GPA would be good because it means you're scoring As and Bs on your assignments. A 2.0 would not be great because it means you're consistently averaging Cs (either lots of Cs on assignments, or lots of Bs and Ds averaging to a C, or some combination like that).

It's possible I messed some of this up because this is stupid and confusing and needlessly convoluted, but the tldr is that yes, a 2.0 and 2.1 GPA are not particularly exciting. That said, Cs get degrees.
