Standardized tests like the SAT and ACT are not good indicators of university success for several reasons: 1) They reduce students to a single test score number and do not account for external factors or a student's full abilities and potential. 2) Standardized tests mainly measure test-taking ability on one day and do not reflect what students have learned over their academic careers or show their work ethic. 3) Factors like wealth, resources for test preparation help, and living situations can advantage some students and disadvantage others independent of their actual capabilities.
