If learning IELTS is often considered a big challenge for students in terms of vocabulary and foreign language learning experience (being used to rote learning, learning tricks or memorizing vocabulary in a fragmented way since childhood), the difficulty for adults is "how to learn English effectively when too busy?", "is it still too late to learn a foreign language when you are too old?"...
To solve this problem, the Linearthinking method developed by the DOL English team - former students of the Gifted High School, Ho Chi Minh City National University - has brought a new approach, helping learners approach IELTS and SAT logically and effectively, reducing dependence on memorization and vocabulary.
Linearthinking is a system of English thinking learning methods, designed by Vietnamese people specifically for Vietnamese people, with a combination of mathematical thinking, super memory techniques and research on the influence of mother tongue on English learning.

According to PhD student Ha Dang Nhu Quynh, Academic Director of DOL English and a second-year graduate of English Pedagogy at Ho Chi Minh City University of Education, as well as a perfect IELTS score of 9.0, Linearthinking not only helps learners improve their language skills but also trains logical and critical thinking, skills needed in an international academic environment.
By applying systematic thinking, learners are guided to analyze questions, find connections between ideas and build strong arguments. This method has also proven effective in solving long and difficult exam questions that require high thinking such as English and mathematics in the recent 2025 high school graduation exam.

The Linearthinking method was invited by the Center for Information and Educational Programs (Department of Education and Training of Ho Chi Minh City) to share with 800 primary and secondary school teachers in April 2025.

"Although it is an English teaching system, we use 100% Vietnamese teachers and staff. First, only Vietnamese people can fully understand the "pain" of learning a foreign language to come up with suitable solutions. Second, we have absolute faith in Vietnamese intelligence. We want to build a product that, wherever we go, we can proudly introduce as a Vietnamese product, from Vietnamese people," the 9X CEO of the DOL English system, where three teachers achieved a perfect 9.0 IELTS score, confided.

Being good at English brings countless benefits
According to the medical website Medicalnewstoday, people who are fluent in an additional foreign language such as English will show signs of memory loss 4-5 years later than people who only speak one language.
At the same time, there are currently 1.52 billion people in the world speaking English. This means that job opportunities or studying abroad for people who are good at English are skyrocketing.
