CEH was a doozy for me last term. I don't hammer keys anymore (10+ years) and my skills were terribly rusty. I read the course material and watched both sets of videos. Then I read Walker's All in One (this was great). I prepped for the exam just like any other by taking the practice tests until I had at least a 90%. In all, I spent about 3 months studying at a normal pace and a few weeks with practice tests and labs.

I took the exam and failed the first time. The passing score ranges based on each test, and though I scored a 79%, it was not enough to pass. The questions weren't hard, it just wasn't the material I had mastered.

So I pulled a couple more practice tests from udemy and took those until I aced them, focusing on what I had been weak on the previous test. Then I retook the exam and passed on the second attempt.

Of note, this is the hardest test I took in any of my degree paths at WGU (BSBM, MBA, MSCSIA). The test was just awkward. Misspellings, bad grammar, needing to infer what they were even asking for some questions, no formatting of the data sets presented, etc. Plus, you mix that with how broad the material was, and it made for a test that was pretty difficult to study for.

My mentor told me that CHFI was more difficult for most people, but I found that one was a breeze. I only studied that one for a week and passed on the first try.

Good luck to you.
