Soldier Move

For the past few years, I’ve been told that schooling and education of free for veterans from the state of Texas. My question is, Is the schooling free via G.I. Bil or by other means. I will be getting out soon and wanna prepare myself. If this helps, these are the awards I’ve earned while serving: Iraq Campaign, Afghanistan Campaign, Combat Action, Nato and others that come with deployment. I’ve also heard you need certain awards for certain privileges as well. Thank you for your time.
