A curious observation regarding my HSK6 Standard Course Workbook marks

[becky82]

To prepare for the HSK6 (again), I began revising the HSK6 Standard Course textbooks, spending around 8 hours studying in depth each chapter (making YouTube videos while doing so).  After finishing chapter 13 (out of 40), I felt I wasn't learning much (I already knew most of the words) and it was rather time-consuming, so I stopped.  Then I started doing the HSK6 Standard Course Workbook exercises instead; these are the marks I got per chapter (there are 36 questions in each chapter, ignoring the writing section):

 

1. 83% 2. 75% 3. 75% 4. 83% 5. 89% 6. 86% 7. 78% 8. 89% 9. 95% 10. 86% 11. 92% 12. 95% 13. 75% 14: 56%

 

I was feeling confident after section 12 when I got my second 95% (on the 5th March, 2024), but then my marks took a tremendous dive at chapter 14 where I got 56% (on the 7th March, i.e., two days later).

 

I'm feeling like this is not a coincidence.

 

(As a side note, two years ago, I thought the HSK6 Standard Course Workbook was too hard, rating it "Difficulty: 9/10".)

I had the same issue when I took an English test. I think there are two reasons for this. First, we may have weakness in our language skills. Second, we still need to adjust our test strategy.
