Depends on what level. I took economics in high school and it seemed like simple stuff. Then again, that was high school.
If you're looking at this as just a college elective, I don't imagine it would be a lot worse than what I had in high school. That also depends a great deal on the teacher, though. I've seen some theoretically easy classes turned into nightmares by hardass teachers.
It's likely to be an easy class, but you won't find out for sure until you're already in it. If I knew your major and your particular affinities, I could probably give a better answer.
