The DSST Subject Standardized Tests are comprehensive college and graduate level examinations given by the Armed Forces, colleges and graduate schools. These exams enable students to earn college credit for what they have learned through self-study, on the job, or by other non-traditional means. The DSST Environmental Science (Environment And Humanity) Passbook(R) prepares candidates for the DSST exam, which enables schools to award credit for knowledge acquired outside the normal classroom environment. It provides a glossary of environmental terms as well as hundreds of questions and answers in the areas that will likely be covered on your upcoming exam, including but not limited to: ecological concepts; environmental laws, policies and impacts; conservation; and more.
