I just got home from the exam and let me tell you, it was tough! I passed with a 759 so i'll take it but it was a very confusing test. Almost like it was written by Dr.Suess or something. What I used to study was of course the Darril Gibson book as well as his online premium content.
His online content was very helpful. Another good site for practice exams that turned out to be wordy and similar to the real thing can be found at exam-labs.com/exam/SY0-401. Using these practice questions along with the Gibson website practice questions was extremely helpful. You need to know his book inside and out though.
Why an answer is right and why an answer is wrong etc.
Well hope this helps you guys. Whew! so glad this test is over.
