I failed the 66 twice using STC materials.  However, for my third attempt I studied the first half of the STC material for (3) days and took the 63 and passed (72%).  However, I failed on my third attempt of the 66.  So, know I ordered STC 65 material and the test questions are very similar to the 66 test bank.  I am scoring high on the practice tests. However, I would like to know if there is better study material and test banks to utilize?  

This week, I just downloaded the Walker "Pass the 65" test bank  and Go/No Go Test.  The first (2) practice tests I failed.  So, know I am concerned.  I didn't read Walker's material but I am going to download from Amazon.  

Is the Walker material "Pass the 65" any good?

Is STC material any good for the 65? 

My desire was to take the 65 next week before the end of the month.  However, I am not feel comfortable doing that and I hate to have to move things back a week; even thought it may be best.
