Rejoice! Wizards and Sorcerers have equal spell progressions. Minimum CLs required are exactly what you expect they are. If your class doesn't gain a spell level because it's too high, this does not change. For example, a bard does not gain a 7 level level casting list, although she will be able to keep up with a full caster until the full caster gains 7th level spells at level 16. Yes, there are no 9th level spells. Tell me
over here what BALANCED 9th level spells you would miss having.

KEY:
Gain x level spells means "Sets your spell progression equal how it appears in the chart upon gaining spell level x "
"—" means "Sets your spell progression equal how it appears in the chart just before gaining the next spell level"
If your class has more than one class level before gaining the next spell level, use the existing chart as closely as possible
If your class does not have more than one class level before gaining the next spell level and you already had a “—“level, then you gain nothing this level
If your class has no more higher spell levels, follow the chart until it runs out (at which point you gain nothing)
