I scored 816/900 but let me tell you, by the time I was finished with all the questions I was just praying for 750!!! I used Prof Messer's videos and study guide, the CompTia objectives, Gibson's book and a variety of mobile practice exam apps (there are actually some diamonds in the rust out there). As some others have already stated, my best advice is the actually KNOW the concepts. That's important on all CompTia exams, but this one especially drives that point home.
Now on to CCENT!!!
