Bikesafe can be excellent, but do not be persuaded to ride any quicker than your experience allows. We've had a couple of riders on our local one who have crashed while trying to keep up with faster riders. Use it as an opportunity to improve your hazard perception skills and anticipation, rather than improve cornering confidence. There is only so much one can learn in such a short time frame; if you are interested in improving your riding, then IAM, or RosPA, are your best bet. It is highly likely that there will be Police riders involved in local groups and you can spend loads of time picking their brains.
