If it's US Figure Skating Basic Skills competition, all you'll get is ordinals. If there are no other competitors in your group, they will all be first-place ordinals, no matter how well you skate. So the scores won't be very informative.
If you're curious, you/your coach can ask the judges to discuss the performance afterward, if they have time. They may not be official judges, but just people with enough knowledge of figure skating (coaches, more advanced adult skaters, advanced older teen skaters) to be asked to judge a Basic Skills event.
So the main reason to do it would be to get experience skating in front of an audience, including an audience of judges. If you have friends or family who might like to see how you're doing, this would be a good occasion to showcase your skills in a format for them watch.
