I've just done my bi-annual after a break of about a year, and my instructor told me to do 60 degree 'S' turns in one direction then straight away in the other direction (whilw keeping a good lookout!). That helped my co-ordination in the turn, and it was lots of fun too. Also try to get used to correcting by the seat of your pants so you don't end up staring at the t&s all the time.
