This exam has been discontinued by DSST and can no longer be taken.
DSST has discontinued the Principles of Physical Science I exam, so it can no longer be scheduled or taken for college credit. We've kept this page up because students still search for it, but there is no longer an active exam to register for.
If you were planning to earn a science credit with this exam, take a look at the similar CLEP and DSST exams below. The physics and chemistry fundamentals covered here — Newton's laws, energy, thermodynamics, waves, and optics — overlap with several of them, and InstantCert's study material for those subjects is available if you decide to switch, so your prep won't go to waste.
