Operator CPC training in Bristol - RHA vs Paul Brown

Has anyone done their CPC with the either of the two organisations?

Generally is there any point to pay £100 more for the RHA course, or do they follow the same syllabus and its just a matter of the trainer on how they deliver it?

Probably been asked a million times, but do you need to do some pre-study prior to the course?

no and no
my cpc was £55 per day including cooked lunch
