What test is the indicator of how well you will do on the ACT?

The best indicator of how well you will perform on the ACT is typically the PSAT or SAT scores, as these tests assess similar skills in reading, writing, and math. Additionally, consistent performance in high school coursework and standardized tests can give insights into ACT readiness. Practice ACT tests can also help gauge your potential score and identify areas for improvement. Overall, a combination of past academic performance and practice test results can serve as a reliable predictor.
