CES exam prep coming from PT background - how different is the ergonomics content?

I'm a licensed PT with 7 years of clinical experience looking to transition more into occupational ergonomics consulting. The Certified Ergonomic Specialist credential seems like the right path. I'm trying to gauge how much of my PT background actually transfers versus what's entirely new territory before I commit to a prep timeline.

The CES body of knowledge covers workstation assessment, task analysis, anthropometrics, ergonomic risk factors, controls engineering, and program management. My PT background gives me solid musculoskeletal anatomy and biomechanics, but the industrial engineering side - NIOSH lifting equations, OSHA recordable criteria, ergonomic ROI calculations - is mostly new. I'm treating those sections as starting from scratch.

I'm planning 8 weeks at 1.5 hours per day. Currently scoring about 65% on practice exams, which is below where I want to be at this stage. The administrative controls and program management section is my biggest gap - it's more policy and documentation than clinical work and doesn't connect to my experience at all.

One thing I didn't expect: the office ergonomics content is very quantitative. Specific chair adjustment parameters, monitor height calculations tied to user anthropometrics, keyboard tray angles in degrees. Much more precise than clinical ergonomics assessment work. Is that level of specificity actually tested heavily or is it more conceptual on the exam?
