Description: A learning-platform theme for English and IELTS sites. Built around a resource hub homepage — test grids, tool cards, course rows and sample libraries — with a dedicated full-width template for the IELTS Tests plugin. Sections are driven by menus, categories and the Customizer, so the homepage can be rearranged without touching code.
