So, when I level up my character in PF1, I choose a new class, add its feature, then skills and feats. But what if I want to add Signature Skill Feat as my level 5 feat. It requires 5 skill ranks in any given skill. But the PRD says
When adding new levels of an existing class or adding levels of a new class (see Multiclassing, below), make sure to take the following steps in order. First, select your new class level. You must be able to qualify for this level before any of the following adjustments are made. Second, apply any ability score increases due to gaining a level. Third, integrate all of the level's class abilities and then roll for additional hit points. Finally, add new skills and feats.
Does the "and" means I upgrade them at the same time, or does this means I add skills, THEN feats, making me effectively having 5 skill ranks in my skill for the feat Signature Feat at level 5 ?
