(CNN)Students across the country are expected to walk out of their classrooms Wednesday morning to protest gun violence. The National School Walkout is scheduled to begin at 10 a.m. in every time zone and last for 17 minutes -- a minute for each life lost in the Parkland school shooting.

If you're a student who's thinking of taking part (or thet parent of one), you probably have lots of questions: Can the school retaliate? Will it hurt your chances of college? Can you just stay home for the day?
