I scored a 75 on this exam about a year ago, with minimal study. I scored highly on the CLEP practice test, so only prepared by going through InstantCert once, reviewing the feedback thread there and reviewing some areas I knew I was weak on using Computer Science Made Simple, from the public library, and a computer textbook website. Total study time probably 8 hours. I've been working with computers at various jobs and as a hobbyist for almost 20 years. Naturally my greatest difficulty was with questions relating to things I haven’t worked with. I probably had 10 questions I struggled with, three of those I finally had to give up and guess. Another 20 or so I marked for review, just to be certain. Some questions are kind of hair-splitty, and easy to over-think. Three questions on psuedocode were unfamiliar (at the time), and a few on system design would have benefited from more time with a book(I've taken the class since), since in real life none of the options 'are FALSE'. I don’t use EDI, so I would have been smart to learn a little more detail on that, and at one point it would have been beneficial to know more about token-ring, but where I come from that's like asking whether you braid the buggy-whip handles to the left or to the right, so…I'm happy with the score. This exam goes a little 'beyond the basics' and probably corresponds to 2nd-year IS course for business people and others who may be taking more computer classes. Based on the exam outlines, this is probably harder than the DSST Intro to Computing. The "Applications" in the exam title refers to applications of computers, not 'software applications', which accounts for the questions about information needs of managers -- some students exporess confusion that these topics appear on the test. That said, it's definitely do-able, though I would recommend additional study if you're new to computers.
