Here's why it's difficult to pinpoint an exact number:
* The movie condenses events: The film is based on a true story, but it condenses a year of school into a shorter time frame.
* Some entries are combined: Multiple diary entries may be combined into single scenes for narrative impact.
* Not all entries are shown: The film only shows select diary entries, and many others may have been written but not included in the final cut.
Therefore, while we can't give you a precise count, we can say that there are many diary entries featured in the film, showcasing the students' personal experiences and growth throughout the year.
