Mitsa Tutoring is a student-led youth organization dedicated to promoting STEM-based education for elementary students interested in studying in the science high schools of the Philippines. We work to develop the scientific skills and knowledge of students and promote STEM education, science high schools, and the pursuit of a STEM career through social media, open-access academic resources, workshops, mentoring, and tutoring. In doing so, we hope to set the stage for the future scientists of the Philippines—for future scientists, by future scientists.
