Congratulations! You and two classmates received an A$+$ on your group project. As you reflect on the process, you make a list detailing why you worked together so effectively. Which of the following statements relate specifically to the effectiveness of your group? Check all that apply.

Before each group meeting, you circulated a brief agenda, because everyone had busy schedules. You also agreed that meetings would be no longer than $30$ minutes.

Early in the semester, the group met with the professor to ensure that your proposed topic would meet all of the requirements for the project.

Each person in the group focused on a different part of the research, so there was no duplication of efforts.

Before starting to do research, each group member reviewed his or her class notes and identified the themes that the professor seemed to emphasize the most in class.
