They will send you an email with an outline of what to expect on the day and they will also tell you not to ask for details about the exercises. Suppress the urge to ask for specifics from previous applicants, they will recognise that you have been briefed and the odds are it will be to your disadvantage. That being said, the basic structure of the day I attended included:
* Verification of online results
* Simulation exercise
* Group exercise
* Behavioral interview
* Briefing exercise
* Spacial awareness test
I used lumosity (suggested in this forum) every day for around a month before, I can't say conclusively that it helped but it certainly didn't hurt. All you can do embrace the experience on the day, you will meet some really interesting and passionate people that are happy to share their stories and experiences. Don't forget you aren't competing against the others so do what you can to be supportive toward the other people on your day. You will feel like a fish out of water but I guarantee you everyone else there is feeling the exact same way even if they don't show it. Good luck!!!
