I did both CCSA and CCSE in the past 2 months. In the most general sense, I'd say the majority of the questions were very fair relative to the course content of each respective test.
That said, I think the biggest problem came from a handful of questions that had different answers for R77.x vs R80.x. For example, there were questions regarding Dynamic Dispatcher and Mobile Access Policies where the multiple choice options presented the correct answers for both versions. In the case of Mobile Access, it was particularly confusing since some policy elements can be managed in SmartConsole and others still have to be managed in SmartDashboard. In these cases, I tried to always go with the R80.x way, but given the number of questions I got wrong, I'm really not certain these answers were scored as correct.
There were also a handful of typos that made the question or the answers very hard to decipher. One Capsule Connect / Capsule Workspace question comes to mind where the choices for Mobile Operating Systems were completely mangled and I had to do my best to try to guess based on the context of everything else in the sentence.
Since I passed both exams, I certainly won't say these issues prevented me from succeeding on the exam.
If this question is being asked to gather feedback to present back to Check Point Training, I'd be happy to discuss things in better detail offline without giving questions away.
Thanks!
