Forum:Class mod + to skill

Class mods have me a little confused... I am not seeing any evidence that the skill +'s from my class mods are active. are the bonuses not allowed to exceed beyond five? and do i get the bonuses even if i have no points allocated to the skill?

lvl 25 soldier Rifleman Class mod lvl req 19 +36% combat rifle damage +2 assault skill +3 overload skill +2 impact

i currently have impact and assault maxed and no points into overload
