"With the Educated perk, you gain two more skill points every time you advance in level. This perk is best taken early on, to maximize its effectiveness."
I have read about two bugs associated with this perk on Fallout wiki so I'll post them here
* 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 14.0 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 16.0 points per level instead of 16.0 and 15.5. While this doesn't necesarrily hurt those characters, one with 9 intelligence similarly only gains 16.0 points per level after the perk is taken at level 4 instead of 17.0 and 16.5 at even and odd levels.
* The perk sometimes doesn't work and you do not gain extra skill points, also you can even lose the extra skill points you gain.
If you guys have any answers or suggestions on how to fix this bug please post them here.
