vietjack.com
VietJack.com is a major Vietnamese education website that combines free textbook solutions, exam preparation, teacher resources, and paid online courses for students from primary school through grade 12.
What can students find on VietJack.com?
The core VietJack.com website organizes learning material by school grade and subject, with textbook solutions, workbook answers, reference lessons, exercises, tests, and examination preparation.
Its platform introduction says learners can access material from grades 1 through 12 covering Vietnam's Kết nối tri thức, Chân trời sáng tạo, and Cánh diều textbook series.
The site also goes beyond ordinary school lessons with preparation material for grade-10 entrance exams, Vietnam's high-school graduation examination, competency assessments, and other major tests.
Does VietJack.com offer actual online courses?
VietJack operates a separate online learning platform with video lessons, textbook explanation videos, quizzes, practice exams, and downloadable learning material.
Its course pages currently advertise VIP access starting from 199,000 Vietnamese dong per month for access across subjects and grade levels, although students should check the current price before paying because offers can change.
The subject range includes mathematics, Vietnamese literature and language, English, physics, chemistry, biology, history, geography, computing, technology, and other parts of Vietnam's school curriculum.
How popular is VietJack.com?
Independent traffic estimates indicate that VietJack.com attracts millions of visits during important periods of the Vietnamese school year.
Semrush estimated 9.95 million visits in May 2026 and 4.32 million in June 2026, with 89.34% of June traffic coming from Vietnam.
The same June estimate placed VietJack.com at number 116 among websites in Vietnam and reported an average visit duration of 11 minutes and 24 seconds.
A Similarweb Vietnam analysis of five large education websites reported that VietJack.com captured 48.1% of their combined traffic in May 2026, compared with 17.0% for Loigiaihay.com and 14.8% for Tuyensinh247.com.
These figures are third-party estimates rather than VietJack's audited visitor numbers, but they show that the domain has substantial reach within Vietnam's online education market.
Is VietJack.com only for students?
Teachers are another important audience because the website provides lesson plans, PowerPoint presentations, examination papers, answer keys, and teaching resources from grade 1 through grade 12.
Its teacher section includes materials organized by subject, grade, and textbook series, which can reduce the time needed to locate resources for individual lessons.
Parents can also use the website to check exercises or understand what children are studying, although the material is primarily structured around students and educators.
How important is mobile learning to VietJack?
VietJack also distributes an Android application through Google Play, extending its lessons and examination tools beyond the main website.
Google Play currently shows more than 1 million downloads, roughly 49,900 reviews, and a rating of about 4.3 out of 5 for the VietJack application.
Semrush also estimated that mobile devices generated 57.24% of VietJack.com's Vietnamese visits in June 2026, suggesting that phones are an important way users reach its educational content.
How does VietJack.com make money?
The website uses a mixed model where large amounts of educational material are freely accessible while courses, books, premium teacher resources, and VIP learning services create paid products.
This approach lets students discover VietJack through free search-friendly answers before deciding whether its more structured paid learning tools are useful to them.
Advertisements are also present in the VietJack Android app according to its Google Play listing, adding another possible revenue channel around its large free audience.
Who operates VietJack.com?
The site identifies its operator as Công ty TNHH Đầu tư và Dịch vụ Giáo dục VietJack, or VietJack Education Investment and Services Company Limited.
VietJack's contact information lists company registration number 0108307822 with an initial registration date of June 4, 2018, in Hanoi.
The registration details are also listed by Thư Viện Pháp Luật, which shows the company as active and names Nguyễn Thanh Tuyền as its legal representative.
What should users know before paying for VietJack?
Students should first test the large amount of free material because a quick answer to one homework question may not require a paid subscription.
For paid courses, VietJack's refund policy states that qualifying refund requests must be emailed within three days after course activation and that approved repayments are processed within five working days, excluding interbank transfer time.
VietJack.com is therefore best understood as a broad Vietnamese learning ecosystem rather than a simple answer website, with its strongest value coming from the combination of searchable free resources, examination practice, teacher material, mobile access, and optional structured courses.
