A "crib sheet" is a concise set of notes or a summary used to aid memory or provide quick reference during a test or presentation. Often created by students, these sheets condense important information, formulas, or key concepts into a manageable format, making it easier to review before an exam. While crib sheets are commonly associated with academic settings, they can also be useful in professional environments. For instance, employees might use crib sheets to summarize project details or key points for meetings, ensuring they stay organized and focused on essential information without needing to remember everything.
