Built by a student, for students

Victor Sindato grew up in Tanzania and was admitted to MIT, Yale, and Columbia during his college application process. He saw how difficult it can be for students to find high-quality, affordable test-preparation resources, so he built thirty-six.co to help remove that barrier.
