Security+ - Difficulty and tips

Hi all,

I am a security analyst and have been working in the security field for three years. I would like to take my security+ in a couple of months and would like to know the difficulty of the SY0-501 exam. Also can you please advise good books and videos to prepare for it? I have been advised the Sybex book: CompTIA Security+ Study Guide: Exam SY0-501.

Thanks,
Jamal
