Is it realistic to clear PRINCE2 exam by just self study i.e. without attending any formal training program?

I answered this last week for someone else so if you have a look at my answers you can see all that responded. 

Here's my nutshell summary: If you are an experienced project manager and can prepare, then yes, you can take both courses, and pass them on the same day. I recommended hand writing practice as the practitioner is a 3 hour written examination.
