As you'll know if you've explored our extensive archive of Advanced HSK tests, these find-the-mistake questions are sheer murder. Your challenge is simple but difficult: identifying which section of a lengthy passage has a serious problem with Chinese grammar or word usage.And while these questions are difficult there is good news too: the points on which they are testing you are not random. These are the same tricks the HSK Committee uses to ferret out non-native speakers. So make note of your errors and remember to review the questions you answer incorrectly using our test center on occasion. And remember: if you have any questions you can always leave us a comment or write us by email at firstname.lastname@example.org.
