Don't do it, try a contacting a contracing company such as MANTECH or ILEX, Booze Allen Hamilton, to name a few, see what they look for. I took some of that at AIT for my MOS. It *****, just a bunch of formulas, I don't remember too many of them, but if you are going to try to get a job at NSA, you should find out more specific what they want, the military and government only focus on a certain part, plus they send all there analysts to courses, master analysis and stuff, some of those courses don't even exist anymore so Ive heard. Yeah but do some research on what NSA actually wants before you just jump into the courses you think you need, you might not need to take any courses on your own. check first, hope that helps
Peace
