Among the professional exams in recent years, which year’s case was the most difficult? Was it in 2014?

Which of the recent actual exam questions was the most difficult? It seems that the approach taken in the 2014 exams was a bit strange
It seems the difficulty order is 14＞11＞13＞10=12
15 is extremely difficult; the pass rate is 0...
That makes sense, haha. There was more content on engineering thermodynamics in the 14th edition, which resulted in fewer questions related to the major unit operations; many people were affected by this, including me :(
In fact, heat transfer is straightforward to score points on, and mass transfer as well as momentum transfer are not very difficult either. The difficulty lies mainly in backwork and thermodynamics.
I took the exam in 2014 and failed the case study section; I didn’t take it in 2015. Was it that difficult back then? :'(
You’re absolutely right; 15 years is such a difficult period – I was too scared to even try taking the exam
The questions in the 15th exam weren’t that difficult; the main issue was the high cost of the exam fee. We really can’t afford to take the exam. After a year of effort, the exam fee in Shanghai has been reduced by 40 yuan this year. Thank you **; now I can afford to take the exam again~
