Advice for students:
Choose your group wisely for the big project. It matters a lot. Participate in your project. Your group members will rate your performance. You don't have to do something too fancy. My project was just mostly front end (since our client wanted to do the backend), so talk to your client about what they need before trying to do something too fancy. Stack overflow is your friend.
