Can someone give me some information about how hard is it,
It is not difficult, as long as you know all basic UML diagrams, like class/sequence/state/deployment/component diagrams.
Most of the questions are scenerio-based, and thus, you have to read some cases, and choose the most suitable diagrams that represent the case.
and how long it take to prepare for it
I learnt UML in my undergraduate days, and I had 3 years OOAD experiences. I used 1 week to read through Fowler's UML distilled 2nd edition to refresh my UML knowledge, and Larman's Applying UML and Patterns to refresh my OOAD knowledge.
