Hi,
I've done this course, I think 5 times ( the company I was with always made us do the complete course each time,rather than just the refresher ).
It also depends which you are doing, I did 1,2,3 & 4 which is Electrical and Instrumentation ( 1 & 2 are Electrical , 3 & 4 are Instrumentation).
Anyway as for the course it comes in a number of parts,
1. Practical Installation
2. Fault finding ( practical )
3. Repair
4. Inspection ( practical )
5. A couple of multi-choice exam papers.
If you are adept at SWA you should have no problem, you also need to be able to do compound filled barrier glands.
The first three days will be in the classroom doing all the theory then a couple of days doing the practicals. If you are there for 5 days, then I would say that would be 1, 2, 3 & 4.
Where are you doing the course? From experience there are places I would rather go to,
Regards.
