Estrazione interrogazioni is an Android app developed by Gianpiero Gaeta, designed to assist teachers in selecting students for questioning. With this app, teachers can create customized lists with the names of their students and always know how many people need to be questioned. Additionally, the app has a "Quick Extraction" feature that allows the user to extract a random number within a user-selected range.

The latest update includes a new feature called "Question Extraction" that enables users to randomly extract questions and view the number and percentage of correct and incorrect answers.

Overall, Estrazione interrogazioni is a useful tool for teachers who want to streamline their questioning process and ensure that students are selected fairly and randomly.
