You won't get an easy ride. Think of the exams as a filter to get rid of the ones who couldn't cope with a TR at the end.
They fill up your head with a huge amount of info., some of it you will never use again. This in itself is a test of endurance and personality. Think of the man in the CAA as a twisted, sick individual. His job is to torment you into failing but traps. If you don't keep reading this info every 9 days, you will forget certain concepts or it will take you too long to work out calculations from formula and tables (probably second nature to an engineer).
My piont: it takes constant revision to master what they are asking you in the question. It is worded to trip you up. Bristol will iron it out, but to have no one to show you how to do e.g.multi leg point of equil time calcs or Departure, Convergency,Grid nav, charts / scale, etc...
Like I say, good luck!
