In today's sample HSK test we present you with a new type of test question. Your challenge in the exercises that follow is to read the sentences provided and identify which section has a serious problem with either grammar or word usage. Sections are identified by letters in parentheses.These exercises are considered more difficult - and characteristic of the advanced levels of the HSK - because they are essentially open-ended. Instead of being given an explicit question, you are presented with a problem and expected to find it yourself. We hope you find these a breeze, but if you have any questions just a post a note below and we'll do our best to help.
