Hi Dave just to let you know this is not from memory and i did have a look on the web.
Hi delboytwo,
Blimey, where do I start with this lot? 
Sorry Del, but you’ve provided a great example of not reading the question, then answering completely irrelevant stuff TWO levels above.
TBF Del, I did say in the question that it was ‘driver’ level and there’s no way you were asked for anything like the answer you gave.

dieseldave:
Q1. What, if any, approval mark(s) are required on the IBC?
first is should have a mark with the letters UN
next should be the type of container IE drum or box, in this case we will say it a drum 1
The correct answer is the letters “UN” in a circle, that’s it, you’re spot-on so stop right there!!
(No wonder you found it hard )
delboytwo:
next would be the material the drum is made of, in this case we will say steel A
then you need to no the category the container falls in so in this case i say non-removable head, 1
than you need the packing group in this case Z
then you need the relative density of the goods we will say 1.2
then you need the test pressure of drum in kPa i do not know what that would be but for this i will say 270
next would be the year of manufacture in this case we will say 02
next would be the country of certification in this case GB
the last bit would be the number of the certificate and as its GB it would be numbers so for this i will say 1234
and this is what it would look like
UN 1A1/Z1.2/270/02/GB/1234
now that was hard hope i got some of it right 
The question related to an IBC, so the code could ONLY start with “31.”
Your methodology was correct in principle, but did you miss the part that says that petrol can’t be carried in a package that has a “Z” in its package code, because it’s in PGII 
[6.5.2.1.1.(c)]

dieseldave:
Q2. Does your ADR licence (the one above) cover you to drive your vehicle to the destination with that IBC on board?
i will say yes as you have class 3
Sorry Del, you appear to have missed the fact that an IBC is a PACKAGE, so the ADR licence I gave in the scenario wouldn’t cover you. 
delboytwo:
dieseldave:
Q3. What, if any, placards/markings are required to be shown on your vehicle?
you would need a red triangle with flammable liquids with the class 3 Orange-coloured plates, with hazard-identification number and UN-Number
hope i got some of that right
It looks like you’ve carried on with the idea that an IBC counts as a tank, so your answer to Q3 is incorrect.
The only markings required on the vehicle would be two plain orange coloured plates, one on the front and one on the rear.
Even if the IBC counted as a tank (it doesn’t,) we don’t use hazard identification numbers (HINs) for UK journeys.
Placards (diamonds) are only required on containers for a road journey, not on the tautliner carrying UN Class 3 in a package as in the scenario.
I had no idea whether you’d done the tanker module when you took your ADR, so I stayed well away from tanker questions out of fairness to you.
Again Del, you scored 1/3, but you’ve got me with the way you knew that the IBC was a package (proved by you looking into PACKAGE codes,) but then went on to count it as a kind of tank for vehicle marking and ADR licencing purposes.
The correct answers were this easy:
Q1. = The “UN mark.” (Cos it’s a package.)
Q2. = NO (Cos it’s a package.)
Q3. = Two orange coloured plates. (Cos it’s a package.)
Are we going for extra time/penalty shoot-out? 
Forget about everything else. Also forget about the fire-extinguishers, because they weren’t stolen and are still fully legal.
