Anyone out there know of IS E4 practice tests online. I am scheduled to take the Sept. exam and would like to do some practice runs. There isn't any study groups where I am as I will be graduating 3910 "C" School a week before I take the test. Any suggestions would be greatly appreciated.
It's unlikely as the IS test is usually classified. Advancement percentage is pretty good though, so just coming out of "C" school you should be in decent shape. My advice would be to do the BMR correspondence course online. You can get to it from https://www.advancement.cnet.navy.mil. You should be pretty good about rate-specific stuff, and that will help you cover the general military knowledge.
Don't fret too much about it, though; you ought to be fine.
