Before You Begin: Requirements for a Smooth Setup

To use the mod to its fullest capacity, ensure the following are installed and up to date:

  • The Sims 4: Seasons Expansion Pack – Required to enable calendar-based school activities.
  • XML Injector Mod – A common utility needed for many script-based mods to function correctly.

Without these, the mod will not appear or function as expected. Install them before launching into any martial endeavor.
