If i join the army national guard do i get to pick the college of my choice?

As long as the college is accredited and on the list of schools covered by the National Guard, you can go to any school you want to as long as you meet the school's minimum requirements for enrollment. Keep in mind that the National Guard has a limit to what they will pay, so if your school's tuition is higher than what the Guard will pay for, you are paying for the rest out of pocket.

no, you have to go to state schools in your state

You can use your education benefits at any accredited school

the military DOES NOT pay for your college. while there are resources, Tuition assistance, and the GI Bill, not all schools are eligible to receive funds from these programs.

MOST NG TA is limited to state run public schools for the whole 'we pay all your tuition and fees' option.
