Maybe you are new to RPG (Role Playing Games) like BD. If that is the case, you will best learn it yourself. You will be well acquainted with the game within 1 week to 1 month depending on how much you play everyday. I am not sure if a trainer for BD exists, so I won't count on it.
Here is the link to a Beyond Divinity Strategy Guide
. This guide is like the biggest SPOILER ever, if not used wisely (or rather sparingly).
