Hi,

I'm currently studying for HSK 6 (汉语水平考试六级), and I am encountering a problem.  Different sources containing practice tests are yielding wildly different results and test scores for me.  Currently I am using the 汉语水平考试模拟试题集 book (it's the one with the green leaves all over the cover), and I always pass these exams, around the 200s to 210s.  However, when I take the Hanban online practice tests, my results are far, far lower, either failing or just barely passing.  It seems more than just a coincidence.  

When I took HSK 5, I remember that brand of book was harder than the Hanban online tests, and the test itself seemed to be have a difficulty level in between them.  This time it's the opposite; the book seems easier than the online tests.  

After this happening a couple of times, I seriously do not know where my level is while preparing for this test.  Is there anyone here who has taken HSK 6 that could possibly shed some light on this for me?

Much obliged!
