CISI Fund Services: UAE FRR vs IISI Regulations

I am currently deep in the revision period for my upcoming CISI exams while trying to maintain a normal schedule at my day job in Abu Dhabi, and I have to be honest I am starting to feel a bit burnt out trying to switch my brain from coding logic to financial banking rules. I have been spending hours on the Fund Services module trying to get my head around the distinction between the various types of client categorization and how they apply when things get cross-border. My grasp of ICWIM is getting better, but I keep mixing up the rules regarding the suitability assessments for retail versus professional clients when the underlying assets are complex structured products. It feels like there are too many small details in the syllabus to track without getting mentally exhausted by the end of the day. My main struggle right now is actually the specific conflict between national standards and international regulations when looking at the depositary functions. I am studying the IISI content alongside the UAE FRR syllabus, and I get halfway through a calculation before I realize I might be using the wrong bandwidth for regulatory reporting based on whether the fund is being marketed in the UK or the Emirates. Does anyone have a specific tip or a way of looking at the fact sheet requirements that helped you separate the mandatory standards needed for the Fund Services exam from the broader context? I am worried that I will freeze during the CME-1 section if I cannot quickly identify which regulation takes precedence in a scenario involving a group of funds with similar mandates.
