During which phase of a well-structured study session is each occurring? One student uses flashcards to quiz another student on vocabulary that may be on the test. The students ask the teacher for clarification on material that the group has conflicting opinions about. One student tells another student, who missed the last study session, what was discussed. Group members write down questions that they think will appear on the test, and then exchange papers.

What are some of the benefits of study groups? Check all that apply.They allow you to do things simultaneously, such as answering text messages while you study with your friends.They help you feel more engaged with the study material because you are part of a community of learners.They let you attend only when you do not have any conflicts with anything else on your schedule.They give you a way to learn from others by listening to different perspectives on topics. They encourage you to think more deeply about the content through conversations with other group members.
