I'm fairly competent with tabletop RPGs. I've played D&D for years as well as others. Recently our GM decided to switch for 3.5 to Pathfinder, which is great, but the core rulebook seems to be organized in a rather confusing manner.
For instance, it took me quite a bit of time to determine my starting XP. But now that I've done that I am having a hard time finding information on leveling.
A bit of help would be much appreciated.
