Final answer:
Open book or open note tests are less challenging than other exams because students have access to their books or notes during the test.
Step-by-step explanation:
Open book or open note tests are usually less challenging than other exams because students have access to their books or notes during the test. This allows them to look up information and reference their notes while answering questions. Open book or open note tests are designed to assess the students' ability to find and use relevant information rather than relying solely on memorization.
