Remember, the Review Questions are a LEARNING activity. They are designed so you have to apply what you learned in the daily lesson (critical thinking) not just finding facts from your notes or flashcards and entering them. Applying what you learned to a new situation, helps you better understand and remember the content.
If you don't think you have all the information you need in your lecture notes or flashcards, don't spend time digging through the reading material or other resources. There is no educational value in that. Instead, use the information you do have and try to answer the question the best you can. It's okay if you get it wrong. The grades for the Review Questions are only a small percentage of your overall grade. The system will give you the correct answer. Add the corrected or missing information to your notes so you have it when studying for and/or taking the exam.
