Well, cpc mod 2 done and passed today. Yay 
Now just mod 4 to do, then on to C+E later in the year. It took so long to book mod 2, I have all but forgotten what the inside of a truck cab looks like now though.
Donāt worry about mod 4, seriously, itās a walk in the park.
I think the examiners realize how patronizing it is. They actually prompt you if youāre forgetting something. Once they ask you a question, if youāve missed something, theyāll be like āAnd what elseā etc, etc.
Also, you donāt have to do it in a truck. I did mine in a 7.5 tonner. Basically a minibus. It was a walk in the park. Got 100% and the examiner looked like he didnāt want to he there.
I have only ever heard of the odd person that has failed their mod 4. I donāt know anybody personally, nor did my trainers, that have failed their mod 4 test. Thereās a really good video on Youtube that goes over every aspect of the mod 4. The guy who does it is called Sean. Really helpful video.
Good luck!
Cheers mate, ill look that video up when Iāve got a few minutes spare. From what I read about mod 4, it does seem pretty straight forward.
