Explanation:
Open book tests are exams during which you are allowed to use your notes, texts or resource materials. Students tend to overestimate themselves in these situations, as they feel like they don't need as much preparation as they do for a typical test. They may not be required to memorize all information needed to pass the exam, but proper organization in order to quickly find data, quotes, examples, and arguments, is necessary, as time during these tests is limited. They should carefully choose the most useful material and discard everything unnecessary, get familiar with the content and the structure of the material, write short summaries, make separate lists with formulas and data for easy access, and use similar techniques to make passing the exam as easy as possible.
