Just want to add to the wealth of information on here for others to benefit from and to help them on there way to get the cert.
I read through Darril Gibson's book Security+ SY0-401 from front to back. I also used ExamCram Security+ for the questions and supplemental info along with professor messer's videos. The process went: read the book, take sample tests, review and study what I missed, take another DIFFERENT test, review and study what I missed. I did that a lot over and over again till I ingrained these concepts in my brain. The test is going to give you situational questions, scenarios, as the course objectives list. Knowing the strengths and weaknesses of every objective item that is listed in the course objectives is crucial. Learn what the items are, what are its strengths and weaknesses, are there any vulnerabilities associated with this system. The more you know about whats on the course objectives the better off you will be, which kinda goes without saying. I recommend getting different books or using other sources to learn more about a certain objective to give you a different perspective and maybe gain more in depth knowledge about a certain system.
There was a lot of guys I tested with that didn't pass or barely pass because they didn't take it seriously. Out of the 17 people that took the test only 8 passed. Some of those that didn't pass included guys that been in the industry for awhile. Soooo... STUDY!!!!
I hope my experience helps anyone trying to get there Security+ cert. The test is tough, but study hard and you will be fine

. Now time for CEH.
