Hello everyone,
First of all, yes, it's a very tough exam, because your brain starts to melt after first 50-100 of "What is the MOST", "What is the BEST", "What is the LEAST appropriate" -like questions.
You have to make critical decisions, clock is ticking and no answer is 100% incorrect. Close to reality, isn't it?
Here are couple of preparation tips:
1) Schedule exam NOW if you really want to take it. This will help you concentrate on your goal and follow the schedule.
2) Avoid official book. There are plenty of books that have information prepared in much better and more compact way (see following).
3) Avoid CCcure. You still won't find any tests that are close to the real exam, so there's no need to waste additional 60-something bucks. Use official app instead which is way cheaper and more convenient to use (especially if you prepare in transport on your way home)
4) Human life first and think like a manager. Write this words on your erasable pad right after you entered testing room. When you have no idea how to answer particular question, look at these words.
Here's how I prepared (in exact order):
1) Cybrary videos from Kelly. As mentioned by other guys here, one of the best free piece of information that you can ever find in your life:

2) Eric Cohrad CISSP 3rd edition. From start to end can be done in one week with 2h/day.

3) Passed all the domains from
https://play.google.com/store/apps/details?id=com.learnzapp.wileycissptests&hl=en. Ensure that you get at least 80% in all domains. Then make a real exam simulation (250 questions) to experience what you'll get on the real exam. Even though this testbank is the best IMO, don't expect questions to be any close to the real exam ones.
4) One day before the exam: refresh your mind with beautiful "Sunflower PDF":

Not so long ago it was updated to 8 domains. Thanks for everyone who participated in writing this summary.
For me this was pretty much enough to be confident (together with 6 years experience in IT Security).
Good luck to everyone!
