Step 1. Write a Google form for students to write multiple choice questions for each other. (https://docs.google.com/forms/d/1nDol6fp5G1QvTXAiTjgJfxVspCJYtDfDr-lqgQ0526M/viewform)
Step 2. Put it into www.askmeqr.com to make it mobile friendly. My link for this activity is http://askmeqr.com/s/c1a854
Step 3. Wait for the questions to roll in. As they appeared I just did a quick check to ensue the answers were right!
Step 4. Copy and paste the questions in to the socrative excel template for quizzes, upload, and run a space race. (Their quiz is at SOC-1561057).
This was the first time I'd tried this with this class, but it worked well, and is something I'll do more of next year.
