Ticks, also known as marks, are small notations used to indicate a choice, completion, or correctness. They are often represented as check marks (✓) and are commonly used in lists, forms, and surveys to show that a task has been completed or an option has been selected. Ticks help organize information and make it easier to read. In various contexts, such as education and assessments, ticks signify correct answers or successful completion of tasks. They can also be used in digital applications, like spreadsheets and project management tools, to track progress and manage workflows efficiently.
