Praxis Physical Science (5485)

The Praxis Physical Science (5485) test is a 150-minute, computer-delivered test of 125 selected-response questions. A periodic table and a table of physical constants and SI unit conversion factors are available as on-screen help screens, and any other constant you need is given in the question. Calculators are not needed and are not provided, so every calculation uses numbers that can be worked by hand.
