As an ex-tutor of TM CPC, I’d just add a few points to the excellent advice already given by Zac_A above.
Regardless of how the discussion about the awarding bodies pans out, anybody doing either the classroom or the home-study version would be well advised the TM CPC cannot be done in a half hearted way. For home study, I’d advise that a quiet room and total lack of disruption during study time is a prerequisite for most people.
For best results, I’d say it’s advantageous (but not absolutely essential) if you’re in some way familiar with road transport before commencing the course.
A person’s own calibre is also a factor.
A rough measure of calibre is that (ideally) the person taking the course needs to be of approx. “A” level standard because that’s the approximate level of what you’re attempting, so one (or more) “A” level(s) of a decent grade.
When I was teaching this CPC, some of the candidates weren’t very good with written English, so they struggled during the course and their exam fail rate was quite (unsurprisingly) high.
A very common reason for failing TM CPC exams, particularly the case studies, was that candidates simply didn’t read or understand the question.
When the question says “list three items that blah, blah blah…” it means make a LIST ( = DON’T write an essay)
When it comes to marking, the markers WILL have read the question, so they will look at the FIRST three things you’ve written. If you’ve written eight things and the good answers are #6, #7 and #8 on your list, then it wasn’t a good idea to have written the first five things.
When you see a question inviting an explanation, they don’t want an essay full of stuff that doesn’t have any influence. For instance, the direction that the truck is facing doesn’t matter, nor does the colour of the driver’s socks or the price of fish. In other words, the answer needs to be succinct AND directly address what’s being asked, so don’t waffle with irrelevance!! A couple of well constructed sentences are normally enough to answer that type of question.
I’m sorry if this comes across as a bit blunt, but it’s true so I might just have saved you from some some future grief and a re-sit fee.
Good luck and please stay focused because SISO applies and so you’ll only get out the quality that you have first put in!!
