Hi Javier,
I believe you are able to move your interview date to a different day and time wihtout penalty, which I recommend you do. It goes without saying that you should confirm that with your recruiter.
For preparation, I recommend 3 three things:
1) Read Case Interview Secrets from Victor Cheng. I would almost go as far as to say: you have almost chance in getting through the day without it.
2) Leverage the boot camp from PrepLouge to get up to speed on the basics
3) Do as many meetings with fellow interviewees as possible (thrugh the PrepLounge meeting board) and possible think about investing in a coaching session (Francesco is amazing, e.g.).
Finally, to help you put my recommendation into perspective, I am currently preparing for an number of final round interviews. I have done a tone of reading and talked to people and coaches and arrived at the conclusion that without preparation it's exceptionally difficult to pass. It's very transparent on what the consultancies expect from you so everybody has a fair chance to convince the interviewers. While that is genereally good, it means that most interviewees have practiced a lot and perform well.
Good luck
