Annual training and assessment 2023/4

Over the last couple of years I've found the training material from the IMI say less than accurate. Well as usual because I am becoming more and more dispondant with the job, stress builds in me each year when I have to complete this training and assessment exam. This year the IMI website material could not be printed, in other words they have produced a "Read Only" version of the training material. There was much too much material to remember after reading through it, although I did read it a couple of times I decided at my age the material was too much to remember. The other problem is that while I was reading through the material I've found that some of the training material is as old as 1997/8, and some advice given in the training material was found to be TOTALLY INCORRECT. This was proven at the end of the training material when a "Mock Test" was provided. One particular question talked about batteries leaking in the training material, and therefore advised that if a battery was seen leaking then the vehicle MUST be refused a test? but that was NOT specified in the answers to the question! Another question asked about the spare wheel and asked what the tester would do with an insecure SPARE wheel in the carrier. Looking through the testers manual and rfr's I found nothing. In my mind the spare wheel not fitted to the vehicle under test is not testable. the rfr's in the testers manual did not provide a MINOR defect for a spare wheel insecure in a carrier, but the exam multi-choice answers did. 

Now let's look at the Dual Purpose Vehicle, which I think as caused some debate on here in times past!

Which statement is correct regarding a Dual Purpose Vehicle? is it...

A/ The unladen weight (ULW) must not exceed 2040 kg, or

B/ The unladen weight (ULW) must not exceed 2400 kg, or

C/ They must be fitted with a permanent rigid roof, with a sliding panel, or

D/ There driving power must be transmitted to all the wheels of the vehicle.


With regards to the training material, what would be considered the correct answer above?

Let's take a look at what was written...

Option B

The vehicle is permanently fitted with a rigid roof, with or without a sliding panel. Therefore C above is correct according to the training material, but answer A is also correct in that we know the unladen weight must not exceed 2040 kg. The question does not ask if we have the unladen weight, its asking which statement is correct. can you see what I'm getting at? 
 
Now I think there has been much talk about the power being transmitted to all road wheels, i.e. 4 x 4, but does the drive have to be transmitted to all wheels? The reason I point this out is because some 4 x 4's (Land Rover) can disengage 4 x 4 and drive in 2WD, but is still a 4 x 4 by design. 

So lets go with the idea that D is incorrect, both answers A and C are correct, which to me makes the question unfair because you can only select one correct answer. The IMI seem to be doing this now year on year. 

Any views on this!!
