The hardest parts of the 2391 in no particular order
C&G speak aka how the question is asked
Pedantry,and marking IOW name something wrong or forget something early in the question and you lose marks for the rest of the question. This means an otherwise really good spark could fail even though he knows his stuff, this is not helped by the IET constantly re-naming stuff fro edition to edition.
Having said that I understand that a line has to be drawn somewhere, and a technical report/description has to be understood universally for other technical people.
Scope, The scope is enormous you can be asked questions on literally anything, it could be something well off the beaten track, or a bit specialist (EV charging points UK Sparks ?
), this is a lot to try and remember off the top of your head, I know as electricians we are supposed to know how stuff is done, but hands up how many sparks know all of the finer points of every special location and/or the more esoteric installs ? not many I would wager.
Nerves, the reputation of the 2391 precedes it, the failure rate is/was already known to be high to anyone taking this exam
The older sparks think the newer sparks should be able to understand everything about everything, but if you look at earlier editions the 15th has next to nothing on testing compared to the 16th, the 17th introduced even more, the regs have ballooned massively compared to earlier editions.
Unsuitable people taking the exam, when I done mine, out of all of us on the course there was only two of us that had previous testing and inspection experience of any note, most of the others had either done none or next to none.
IMO the course was designed for candidates who were already T&I ing, it is not designed to teach you how to T&I
urs was used by the students from the college , it was in a helluva state lol.
