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 Introductory College Algebra Passbook® prepares candidates for the DSST exam, which enables schools to award credit for knowledge acquired outside the normal classroom environment. It provides hundreds of questions (with solutions) in the areas that will likely be covered on your upcoming exam, including but not limited to: rational expressions; linear and quadratic equations; functions; graphing; and more.
