Our verdict
VietJack is useful for students and teachers who need textbook solutions, sample essays and exams by grade, mostly free to read. The trade-offs are ads in the free version, content built for lookup rather than a personalised study path, and a refund policy that does not cover VIP.
Best for: Grade 1-12 students who need textbook and workbook solutions and practice exams
Skip it if: Learners who need a personalised study path or live tutoring
Pros
- Broad coverage: textbook and workbook solutions, essays, lesson plans, lectures and exams from grade 1 to 12

Cons
- The free version shows ads; removing them requires VIP
- The VIP page is inconsistent: the price table starts at 250,000 VND but the FAQ says from 199,000 VND, and exam counts differ between sections

Problems it solves
Experience & key features
VietJack is a general-education website run by VIETJACK Investment and Educational Services Co., Ltd. in Hanoi, which received its business registration certificate on 4 June 2018. The homepage calls it Vietnam's most-visited education website; the sources read offer no independent figure to verify that.
Content includes textbook and workbook solutions, sample essays, lesson plans, PowerPoint lectures, exams and exercises for grades 1 to 12. Teachers can build exams from PDF/Word files, shuffle them into several versions and assign tests. VietJack's about page lists five parts: a free library, the khoahoc.vietjack.com learning and testing site, a Q&A forum, an app and a YouTube channel.
Most solutions are free to read, with ads. VIP on khoahoc.vietjack.com costs 250,000 VND for 1 month, 399,000 VND for 3 months, 599,000 VND for 6 months and 799,000 VND for 12 months. It unlocks all practice rooms, exams with answers and VIP lectures, adds DOCX downloads with answers and removes ads. Figures on the page do not match: the overview claims 200,000+ exams and 3 million+ questions, while the FAQ says 100,000+ exams, 2 million+ questions and prices 'from 199,000 VND'. Payment options are VNPAY QR, domestic cards, international cards and the VNPAY wallet.
VietJack suits lookup and exam practice for the national curriculum. For assigning and grading tests online, see Azota; for a structured course path with lectures, compare OLM or Tuyensinh247. On data, the policy says servers are in Vietnam and nothing is shared externally unless the law requires it or the user consents.

Why this score
Content is organised by grade and subject with search; rated 4.2/5 on Google Play and 4.4/5 on the App Store. Points off for ads in the free version; no independent interface review exists. The interface is Vietnamese-only.
Why this score
Wide material coverage and teacher tools, but oriented to lookup; the sources show no adaptive learning or AI grading.
Why this score
Core material is free; VIP costs 799,000 VND/year (about 67,000 VND/month) or 250,000 VND for one month, and courses have a 3-day refund. Points off for ads in the free version and inconsistent prices on the page.
Why this score
Ratings of 4.2/5 on Google Play (about 50,000) and 4.4/5 on the Vietnam App Store (about 17,000) suggest fair satisfaction; the iOS app was last updated on 18 Dec 2024. There is no independent data on speed or solution accuracy.
Why this score
Phone, [email protected] and Zalo chat (advertised as 24/7) are offered, with no response-time commitment.
Why this score
The policy lists data types, Vietnam-based servers and no sharing except by law or consent, but shows no effective date and no specific retention period.
