Is 391 a good credit score?
It's just aweful. You need at least a score of 650 or higher to get most home loans and car loans at reasonable rates. Try getting some secured credit cards to raise you score.

Is 215 a good score?
If you are talking about credit score, understand that I am not a credit expert, but since a credit score of 620 is bad, 215 would be a terrible credit score. If this is for a test like the SAT, this is also horrible. The average score of the SAT is about 500, and even that isn't that good of a score.
