This is a popular exam even when it was called Environment and Humanity, and the good news is that it's not particularly difficult. Environmental issues have been at the forefront of public awareness lately, and it's fair to say that Americans today are highly environmentally conscious. The challenge, as always, is balancing industrial progress with responsible stewardship of our planet. Coincidentally, that's exactly what this exam covers. You could have taken the old one with mostly common sense, but the updated version goes much deeper. You'll see the usual environmental talking points, but it does explore some technical areas that may be unfamiliar to many. Check out our feedback forum for some examples of what others wished they'd have studied. Also, it might be a good idea to take this one before tackling the Natural Sciences CLEP or the Biology CLEP if those are on your list. Both of those exams include earth science content, and your study for the Environmental Science DSST will give you a solid head start.
