Sorcadin Build Assistance

[Cranthis]

Hi there, first non-obligatory post here. I'm looking for general help with my latest build, the Sorcadin.
Build so far:
Race: Draconic, Magic blooded, Lesser Aasimar

Levels: 7 Paladin 2/ Sorcerer 4/ Spellsword 1 (Going for the standard, finishing out with Abj. Champ5/ Sacred exorcist 8)

Abilities: 32 point buy
Str: 12 (14 after race), Dex: 12, Con: 14 (16 after race), Int: 10, Wis: 8, Cha: 18 (24 after race)

Feats:
1: Power Attack
Flaw: Combat Casting
Flaw: Versatile spellcaster
3: Theurgic hands (Homebrewed, stacks paladin and arcane class for lay on hands and smite.
6: Leadership (Cohort is a Dragonfire Inspiration focused bard, to help buff my damage)

What I need help with is skill allocation for the most part, in order to meet all of the pre-requisites for Sacred Exorcist. It requires more ranks than I believe have, due to all the cross class, but I have seen people manage it anyways. I've tried doing the math, but I'm just too scrambled.

Any other advice is greatly appreciated as well.

if you're going for sacred exorcist, you should take southern magician. opens you up for divine metamagic.

Right now two things come to mind:
Education feat: Gives every Knowledge as class skills
Domain Access Sorcerer: With the Knowledge Domain, you have all Knowledges as class skills for your Sorcerer Levels

It depends on how flexible you are with your feats.
If you are adamant in keeping your selection, then the best bet is to start as a Domain Acces Sorcerer and focusing in Knowledge The Planes and Arcana for the first 3 levels of paladin (You will have only 2 skill points) And then ditch Arcana in favour of Religion.
