Unit tests are tests which tests students' understanding of a topic. They are given at the end of each unit before the next unit. They are usually more difficult and worth more than regular quizzes and tests. Students have to study more often to get a good result. These unit tests eventually lead up to a final exam at the end of the semester. The contents of a unit test have most of the things students learned in that unit. They are similar to the questions on the assignments, but they are not the exact same to prevent students from breezing through the test. These tests usually require all of the class time to complete. Any students still doing the test will not be allowed to leave until they do so. Furthermore, most unit tests are not multiple-choice, so students will have to figure out the answer without brute-forcing the solution.

When students are finished, they can do whatever they want quietly. Many teachers use dividers to prevent as much cheating as possible. Sometimes, dividers are not enough; many teachers will walk around the class.
