Skill maximums

By Athelys, in Star Wars: Edge of the Empire RPG

So Ive been finally reading the EoE core book to learn the game, I see where characteristic top out at 6 but I cant seem to find any info on what skills cap out at. Is it 5 or can they go as high as you want with the expenditure of a ton of xp?

Thanks in advance and sorry if this has been asked already

Skills cap at 5. Although there are some things, like a couple of armour attachments/mods that can raise them above this level.

cool thank you for the information

As with Characteristics, skills can hit 6 if you have a piece of cybernetics that gives +1 to a skill.
