How to Get Cold-Called

A simple, three-step guide:

1. Begin doodling in your notes. Be careful to use simple, repetitive pen motions that look nothing like writing, even from a distance.
2. Wait for the person in front of you to ask a question.
3. Continue doodling while the professor answers the question.

For best results, maintain just the right balance between showing weakness and knowing what you're talking about. Properly executed, this can keep the professor's attention for up to twenty minutes.
