I failed the HSK!
Failing the HSK really only has one effect: You have to take it again.
Many students fail the HSK, and it’s usually not a big problem. A poor grade on one HSK test will not affect your score on others. In fact, if you fail an HSK test, you won’t get an HSK certificate, so no one will even know you’ve failed.
The best solution to this problem is to study harder next time and retake the test.
