Mine certainly wasn't particularly intensive. We only glossed over a few areas of the pams. It's a lot to cover in a short space of time. Most of it was practical. Make sure your drills are up to scratch. It helps if you can shoot reasonably well too.
Mine was done entirely on the DCCT as some numpty had closed all the ranges for safety reasons. Once you have the qual, do your best to make it known to your unit so that they actually use you. I've barely done any coaching in the two years since I did mine.
