This is one of the easier DSST exams and should ideally be taken alongside the Introduction to Law Enforcement exam if possible. The overlap between the two is significant, so taking them close together maximizes your chances of retaining the material needed to pass. Obviously, those with a law enforcement background will have an advantage, but anyone can pass with some dedicated study. The material isn’t difficult, but it does require memorization of past court cases, along with knowledge about prison populations and citizens' rights. Don't get too lost in the weeds when it comes to court cases. If you've taken the American Government CLEP, you'll see many of the same cases dealing with civil rights again.
