For the majority of the past levels I have only had 16 skill pts to spread - and this figure has not risen for a while (I took Educated early on for obvious reasons). If I'm not mistaken, Educated will add +2 skill points each time you gain a new experience level.
Is there a cap of some sort or am I missing something painstakingly obvious?
Adds to the experience gained I think, not how many points u get when your reach a new level. As in it speeds up how fast you gain experience points to reach the next level. I think...
EDIT: actually I think I'm thinking of the swift learner perk

If there is such a perk
EDIT:Actually your right, The Vault wiki says +2 skills points per level...hmmm.
