What percentage of college students have never missed a test or done poorly on an exam because alcohol use?

There's no definitive data on the exact percentage of college students who have *never* missed a test or performed poorly due to alcohol use. Such data would require comprehensive, self-reported surveys with extremely high participation rates and honest responses, which are difficult to achieve.

Studies on alcohol use among college students consistently show that a significant portion engage in risky drinking behaviors. While some students may abstain completely, or drink responsibly without academic consequences, a substantial number experience negative academic impacts from alcohol, including missed classes, assignments, and poor test performance. Therefore, the percentage of students who have *never* experienced such consequences is likely a minority, but the precise number is unknown.
