UAE FRR: Central Bank vs Free Zone Licensing Requirements

Hi everyone, I am honestly drowning in revision at the moment. I am an HR manager in London right now but I have to relocate to Saudi Arabia next year for a new role, so I need to secure my CISI qualification first. I decided to tackle the CMA Saudi or the UAE FRR to start with but the sheer volume of new legislation is overwhelming me. I feel like I am trying to memorise a textbook rather than learning the actual subjects. Does anyone else feel like the syllabus changes too fast to keep up with? My main stumbling block right now is the specific fiscal and AML regulations listed in the UAE FRR handbook. I am confused about the difference between the Central Bank of UAE licensing requirements versus the local free zone authorities. The differences in permissible activities seem so technical to me, especially regarding remittance services. Could someone break down the specific threshold for capital requirements or reporting duties that trigger the full regulatory compliance checks? I need a better mental model for these rules to stop second guessing myself during mock exams.
