怎么说?难度与含金量成正比。。。确实难考。。努力,毅力吧。。
Yes, I totally agree with you.
As far as your question is concerned,
it depends on how much energy is delivered to the project.
It is obvious no pain to gain.
One thing for sure, thousands candidates pass the exam each year.
So, after confirming with yourself the decision.
Keep rolling until you make it.
Good luck.
