Pathfinder Disable Device

[Snig]

I'm using PC Gen to create a character. I have a question I can't figure out about my skills.

When I put a point into Disable Device my modifier goes from 3 (dex mod) to 7 (I think I get 3 points for selecting it? but i'm still not sure how I get 7?) And I also get the skill Disable Device (traps) which gives me a total modifier of 10!

Anyone know how to explain these Misc Mods?

If it's a class skill you get +3 for the first rank of getting a skill in Pathfinder.

In 3.5 you originally had x4 ranks on level 1, so Paizo decided to cut out the Middle Man in pathfinder and instead making skills 1 rank per level instead of x4 on first. To compensate, the first rank in any class skill adds a +3 misc bonus.

Cross-class skills can be raised too, at 1 level per rank, but do not get the +3 class skill bonus.

do you know why disable device (traps) gets a +6 misc mod, while just disable device only gets +3?

Did you take a level in rogue or another class with the trapfinding ability?

We need race and class data.

Any archetypes, or just the Base Alchemist? Did you grab one of the gnome racial traits that affects Disable Device?

We know that you've got 1 (rank) + 3 (trained) + 3 (Dex), so there's got to be 3 more that are floating out there as a result of another option you took. A gnome with the Master Tinker alternate racial trait and a trait like Nimble Fingers could add a couple more points, and the Trap Breaker archetype would add 1/2 your level (which I believe would be calculated as minimum 1), so that could get you there.
