Abbreviations: PCAT = Pharmacy College Admission Test; R² = coefficient of determination; SS = scaled score; CL = conventions of language; PS = problem solving; GPA = grade point average; Age = candidate's age on Aug. 1, 2008; All Other Demographic Variables = student's sex, ethnicity, native language, citizenship, parents' education, previous level and type of school attended; PCAT Scores = all subtest scores combined; Unst. = unstandardized regression coefficients; Stand. = standardized coefficients estimates; All Demo. = all demographic variables available; * = no significant contribution
Writing CL and PS scores were dummy variables set as 1 when greater than or equal to 3.0 (otherwise 0). All demographic variables except age were dummy variables (either 1 or 0).
