Although English is the primary medium of instruction in most subjects in the Philippine education system, Filipino is taught as a subject under the DepEd-prescribed K to 12 curriculum for basic education. Filipino as a subject is also taken up by University students pursuing Bachelor degrees in Education.

This reviewer contains review materials in Balarilang Filipino (Filipino grammar), Talahulugan sa Filipino (Filipino vocabulary), and Panitikang Filipino (Filipino literature).

Special reviewers have been designed specifically for non-Tagalog speakers, including foreign student and non-Tagalog speaking Filipinos who may have difficulties grasping the lessons if presented entirely in Filipino.
