What is blue books for exams?

Blue books are small paper notebooks that are used for taking exams or writing essays. They have two covers, typically a blue cover for the front and a white cover for the back. The pages inside are usually lined or blank for students to write their answers on.

Blue books are commonly used in higher education institutions, especially in the United States, as a way for teachers and professors to administer exams and tests. They are also used for in-class writing assignments, where the students are given a prompt and must write a response within a certain time limit.

Blue books are often collected by the teacher or professor after the exam is completed, and graded at a later time. This allows for anonymity in grading, as the students' names are not typically written on the blue books.

While blue books are still commonly used for exams, digital alternatives such as online exams or quizzes have become more popular in recent years, especially with the rise of online learning.
