How'd you manage to max out every skill?
* = Implant
Strength 1+1* (Melee Weapons +4) = 4 points.
Perception 9+1* (Energy Weapons +20, Lockpick +20, Explosives +20) = 60 points.
Endurance 7+1* (Big Guns +16, Unarmed +16) = 32 points.
Charisma 1+1* (Barter +4, Speech +4) = 8 points.
Intelligence 10 (Medicine +20, Repair +20, Science +20) = 60 points.
Agility 4+1* (Small Guns +10, Sneak +10) = 20 points.
Luck 8+1* (All Skills +5) = 65 points.
(4 + 60 + 32 + 8 + 60 + 20 + 65 = 249)
Four tagged skills (with Tag! perk) = 4 x 15 = 60 points
Leveling from level 1 to 4 = 3 x 15 = 45 points
Leveling from level 4 to 50 (with educated perk) = 46 x 17 = 782 points
Skill books (with comprehension perk) = 65 x 4 = 260
So, 249 + 60 + 45 + 782 + 260 = 1396 (with 1300 you are already maxed)
