Well I passed the exam and yes, I'm happy I passed, but not happy with my score. To me the score is a direct reflection of how much you understood the material and well... I thought I understood majority of the material well enough to score over 800.
I'm happy to say I'm Security+ Certified, but wanted more reassurance I understood the material to test well.
My exam was very technical, few 'administrative' questions. Several questions about Cloud computing and other things that I don't remember in DG's book, but hey, I passed and I can only get better!
My recommendation after taking the test now is to not only study DG's book, but to find other study materials as not everything is covered in one book. And for not being a 'technical' person, I'm pretty proud of myself for passing a 'technical' exam!
