What you're remembering is from pre-3e. Before 3.X, specialist wizards got +1 to the DC of their spells. Evokers were scary. That was removed with 3.X. Instead, you get a bonus spell slot to prepare one of your specialist spells.
In 3.X and PRPG, a 5th level evoker, for example, has access to 3rd level spells. She could prepare burning hands, scorching ray, and fireball in addition to her normal allotment of spells.
