How many times must ya person read something before they remember it?

The number of times a person needs to read something to remember it can vary widely based on several factors, including the complexity of the material, the individual's learning style, and their prior knowledge of the subject. Generally, concepts can be retained better with spaced repetition, which suggests reviewing material multiple times over increasing intervals. For some, it may take just a few readings, while others might require more extensive practice to achieve retention. Ultimately, effective engagement with the material, such as summarizing or discussing it, can significantly enhance memory.
