I did the refresher course at Bristlecone for my renewal which I just applied for online. Was stupid easy. Basically you shoot something like 30 rounds at an ipsc style target and a certain percentage have to hit within what would be the C zone. Then the classroom consists of a multiple choice test which is taken as you run through a number of slides which includes all of the current/new gun laws that have gone in to effect over the last 10 years. No one in the class failed.
