For those that just are having a really hard time passing it, I felt like that after taking this exam 4 times! The key is never give up!!
I realized I wasn't really understanding my weak domains, Legal, Operations, ISM, and Operations as much as I did the others. I didn't pass my 3rd time at 688 and my 2nd time at 680.
Do the following if you are stuck on more abstract and not memorization type domains like telecom and crypto.
Use this test engine. CCURE can help, but I think this test engine was great

Also, use the CBT nuggets videos to review, this help me get the bigger picture instead of following the little details that I focused on so much instead of the bigger picture!
Good luck to you all!
