A substitute teacher lacks prepared lesson plans and needs reliable, ready-to-use EFL teaching materials and activities for classes where no sub plans are provided.

Existing EFL websites are scattered and not integrated for quick, no-prep sub lessons; many are in Norwegian or untranslated, limiting their use in English-language classrooms.
