This is an exam with a long and storied history. When I first took this DSST, it was called "Here's to your Health" and was one of the easiest ways to get upper level credit available. Around 2010, they updated the exam and made it much more difficult. A bit later, ACE dropped the recommendation for upper level credits and most schools will now only award lower level. All that being said, it's still a relatively easy exam in the grand scheme of things and is popular for those looking for elective credits or for health related degrees such as sports medicine, etc.
