I took I-net+ exam last week and passed with 870. I've used uCertify
exam simulation. If you read these study guides and simulation, you
will be fine. uCertify test questions were very tough and follow the
test questions pattern, most of questions I practiced before. I've
taken uCertify up on their 100% pass guarantee. Now I'm working on my
next cert. Click the link and look at it http://www.ucertify.com.
Really you'll find good stuff for most of certification exam. Good luck
to all who are preparing for cert exam.
