Biological Processes and Chemical Processes: 40% of the items in each of these two subtests (formerly called Biology and Chemistry) are associated with passages that focus on a specific research study or experiment requiring content knowledge and analytic skills to interpret and evaluate.
Critical Reading: 40% of items in this subtest (formerly called Reading Comprehension) include items that require the interpretation, analysis, and evaluation of passages with humanities or social science content.
Quantitative Reasoning: This subtest (formerly called Quantitative Ability) includes a greater proportion of items on basic math and algebra content, with fewer items covering precalculus and calculus. Also, 50% of the items in this subtest involve a practical scenario or situation and pose a quantitative problem that must be solved.
Use of a calculator and a periodic table: An online standard calculator will be provided for use with the Biological Processes, Chemical Processes, and Quantitative Reasoning subtests, and a periodic table will be provided for use with the Chemical Processes subtest.
Verbal Ability: To allow additional time for the Biological Processes and Chemical Processes subtests without lengthening the overall testing time, the Verbal Ability subtest is no longer part of the PCAT.
