I'm with you, my test is early this week. One of your previous posts was asking about info on the ASVAB... but in this post you are asking info for the ASTB. Here is a link to the ARCO book that I think you may be looking for. Its for the ASTB (not the ASVAB - thats something totally different - but since you are posting on this web site I assume you mean ASTB):
http://www.amazon.com/exec/obidos/tg/detail/-/0768910293/qid=1050284332/sr=1-1/ref=sr_1_1/103-5631602-4534262?v=glance&s=books
you may have to copy and paste it. if you dont have time to order it, at least you will know what it looks like. most public libraries have a copy (proabably an earlier edition though - but has the same material). you can also download the 4th edition off the web... you cant print it though which blows... but its a worse case senario option. the link is:
http://www.petersons.com/airforce/books.html
i think its fourth from the bottom. may also want to take a look at the Officer Candidates book at the bottom of that link as well.
but from reading the posts on this site... the mother load of info is in the three files that you can download off of this site. Click on Resources from the bar above--> File Lister --> Gouge --> Go to page 4 of 4 --> the download ASTB Gouge, ASTB1, and ASTB2. they are all pdf documents. apparently you should study these inside and out. the ARCO books you are trying to buy, from what i gather from the posts, is only good for studying the Mech Comp, and Spatial sections. hope this helps.
