The regs is like a J.R.R Tolkien book in the complete wrong order...... or so it seems until you start to get to grips with it and the way it is structured. Taking the 2382 doesn't mean you know the regs inside out, it means you can navigate it at most. It comes with experience (or at least additional knowledge), not a 20-day training programme.
When I started in the trade I read around about 50-60 books on electrical subjects, cover to cover, most twice and the better ones 3 or 4 times. And I wouldn't say a tenth of the information went in, let alone made any sense. It was only with practical experience that things started clicking into place, and things became a lot more logical to me. I passed the 2382 with 100% after a couple years practical experience, I'd probably have passed it without the experience years ago with lesser marks, and I would be confident I could pass it now without even opening the book (as many on here could) - but my point is, it doesn't really count for much. Not to p*** on your chips or anything, but as with most trades it's more than a qualification. Without experience you'll struggle (as you have shown).
So where do you go from here? First up, sign up to the trainee section as
@Specialist has said - there's a whole section dedicated for us trainees and you'll get some great advice from carefully selected mentors (most of them have forgotten more than I know). Second up, get experience with a spark. Forget about these 'boil in a bag' courses (thanks to
@Pete999 for the name) and learn hands on. Once you've got a bit of experience start thinking about backing it up with some knowledge, the 2365 L2 or similar. Qualifications are the perfect partner to experience, hence why NVQs are still the sought after qualification. One without the other will make an impossible task ahead.
