Hi SPHR Tester in New York,
If you are still checking this forum, I passed my SPHR on December 22nd, 2014.
1. The actual test was far more complex than the practice tests and I was befuddled at times.
2. I have not received my final exam scores, but I scored fairly high on the practice tests and assessments - 80-90% at the end of my study period.
3. Study was very intense - practicing the tests improved my practice tests, but did not fully prepare me for the actual certification
Hopes this helps. I think the bottom line is how well of a test-taker you are.
