About 8020 Education
8020 Education is the international brand of the team behind 8020 English, a test-prep centre in Ho Chi Minh City led by an academic head with over ten years of IELTS and SAT teaching. We built 8020 Education to teach students in every country, online, with the same tutors and the same standards.
Why “8020”
The 80/20 principle says a small share of causes produces most of the results. In test prep, a few skills and question types decide most of a score. We find those first, so every hour of study counts.
