I have taken 5 of the 10 tests for Advanced Certification. Doing one per week and have no clue yet as to

whether I am passing or not.  Am doing one test per week. 

I have passed the CPA exam on first try,  and I am quite irritated about the following:

1.  The answers to about 30% of the questions cannot be derived from any training material,

 nor from any other instructional texts found online.

2.   The test instructions are not clear. Example: Which 2 statements below are correct (choose all answers  

 that apply)? That is a serious test-designing mistake. Is it "2" or "all"? It shows me that  employees who are not trained in analytical thinking designed question/answer.   

3.  There are sentence structure- and grammatical mistakes in every section's test. They dilute the test taker's focus. 

In my opinion it takes a portion of good luck to pass this test.  That's not acceptable for such complex material.
