The service
Exam Trail Hải Yến (run by Hải Yến) lets you take computer-based mock tests and learn 1-on-1 with a teacher: tests are assigned, taken, marked and reviewed here. Fees and schedules for 1-on-1 lessons are agreed with the teacher directly, not through this site.
Accounts
- Students join a class through the teacher’s invite link. Each person uses an account of their own.
- Keep your password secret; you are responsible for what is done with your account.
- Students under 16 need a parent’s or guardian’s agreement.
Fair use
- Do not share, copy or republish the tests, answers or materials in the app.
- Do not take tests for someone else, try to reach other people’s data, or disrupt the service.
If you do, the teacher may close your access.
Content and copyright
Tests and materials are for your own practice in the class. Your answers stay yours; you let your teacher use them to mark and review your work.
IELTS is a trademark of the University of Cambridge, the British Council and IDP; SAT is a trademark of the College Board. This site is not affiliated with them.
Scores
Mock test scores are practice estimates, converted with commonly used tables; they are not official scores and do not guarantee a result in the real exam.

Changes and ending
