AUSTIN, Texas - It's a nerve-racking time for high school seniors as they wait to hear back from colleges they've applied to. This year, there's an added factor causing some students concern.

They're worried that participating in walkouts for stricter gun laws could jeopardize their college chances. That depends on which school you decide to apply.

As of Monday morning, there were more than 50 universities nationwide that said taking part in a walkout won't affect admission. In fact, some of them applaud it. Three of them are Texas universities: Rice, Southwestern University in Georgetown and Trinity University in San Antonio. Academic bigwigs - like Harvard, Yale, MIT and Northwestern universities - also made the list.

Aside from grades, colleges also look at community service and whether or not you've been in trouble. Some school districts warned students that if they decide to walk out or protest during school, they could face disciplinary action.

Northeast ISD in San Antonio sent a letter to parents saying that students who take part in protests would get an unexcused absence. However, Austin ISD gave students some time to participate.
