The 51% first-time pass rate DOES NOT mean you have a 51% chance of passing.

It's not a coin-flip. If you were taking the exam 10 times in a row, if you fail the first try, you should expect to fail the next 9. If you pass the first time, you should expect to pass the next 9.

If you fail, you should expect to fail again indefinitely until you change something about your responding. Usually, something big.
