DSST Environmental Science or DSST Astronomy?

Is DSST for anyone or one must be active duty?

Anyone can take an exam, you just have to find a testing center that is "open" rather than "limited."  Some schools are limited to their own students.  Some testing centers are limited because they're on a base.  But other than that, you should be fine.

Thanks, I didn't know that, this opens up more options for me. I will look into it.
