Zodiac Signs!!!

Signs sitting in a boring class:

Phone under the table: Sagittarius, Taurus, and Leo
Fell Asleep: Virgo, Aquarius, and Cancer
Aimlessly turning a pencil in hand: Capricorn, Pisces, and Libra
Creating a plan on what to do if the teacher suddenly turns into Voldemort: Aries, Gemini, and Scorpio

Personally for me, this one isn't true.
