Like previous games, this perk works best when obtained early in the game.
With high Intelligence and the Comprehension perk, this perk becomes less useful, as you will easily max out your skills. By level 20, you can max out your skill stats with reading around 250 of the total 324 skill books, leaving you with almost 75 extra skill books left over.
xbox360 The 0.5 modifier that comes with an odd numbered intelligence can sometimes cause Educated to bug out if the perk is taken. A character with 7 intelligence for example will possess 14 and 13.5 skill points per even and odd numbered levels prior to the perk, however after taking this perk at level 4 the character instead gains 16 points per level instead of 16 and 15.5. Conversely, characters with 9 intelligence only gain 16 points per level after the perk is taken at level 4 instead of 17 and 16.5 at even and odd levels respectively. [verified]
