The team and students behind the scores

How you study

Three ways to learn with us

Private 1-on-1

Lessons built entirely around one student: their gaps, their test date, their time zone. Best for a fixed deadline or a specific target score.

Small groups

Students at a similar level, live online. Lower cost per hour, with the energy of a class and individual feedback on every assignment.

Full courses

Structured programs from foundation to exam day, with mock tests at each stage. For schools and partners, we also run courses for whole classes.

The 8020 method

How we raise a score

  1. Diagnose

    A timed diagnostic test shows exactly which question types and skills cost you points.

  2. Prioritise

    We find the 20% of skills that will move 80% of your score, and build the plan around them first.

  3. Practise

    Live lessons, homework marked within days, and full mock tests under real timing.

  4. Report

    Students and parents see attendance, homework and mock results, so progress is never a guess.

Questions

Where are you based, and where are your students?

8020 Education is a brand of Testlyn LLC, a US company registered in Wyoming. Our teaching team grew out of 8020 English, a test-prep centre in Ho Chi Minh City. Lessons are online, so students join from any country; we schedule around your time zone.

Are the reviews and results on this site real?

Yes. Every score and quote comes from an official score report or a message in our own class chats, shared with permission. We blur names and faces and link each quote to the original screenshot. Families mostly write to us in Vietnamese, so the English quotes are our translations.

How much does it cost?

It depends on the format (private, small group or full course), the subject and the number of hours. We quote after the free consultation, once we know what the student needs. There is nothing to pay to talk to us.

Can parents follow progress?

Yes. Parents receive attendance, homework and mock-test results, and can message the tutor or the academic head at any time.

What if the tutor is not the right fit?

Tell us and we will switch tutors. The consultation exists to get the match right from the start.

Free consultation

Tell us where you are. We will plan the rest.

Share the exam or subject, your target and your test date. We reply by email within one working day with a suggested tutor, a class format and a first-lesson plan. Fees are quoted after the consultation.

  • Private lessons, small groups or full courses
  • Online from anywhere, scheduled around your time zone
  • A diagnostic test before the first lesson
  • Parents see attendance, homework and marks
