Is it easy to take the national post exam now?

As a fitness instructor who has worked in the gym for many years, I think the national title examination is getting more and more difficult. A few years ago, some of the fitness instructors we recruited were self-taught and passed the national title examination. Now many of them have received professional training and tried to pass the national professional title examination. Some of them seem to have studied in the Asian Institute of Physical Fitness, and their school pass rate is quite high.
