No need to change too much, keep working hard putting the hours in, as much P2P as you can fit in, work the daily sheets & pick up new points.
Mr Thomas 21's Bankers are slightly different there's probably 20-30 (including reverses), learn them if you haven't done them already.
In my view examiners are not necessarily looking for tighter lines but good fluency on 21's, so keep doing what you're doing (oh & try & avoid Mr P!! he can be pretty ruthless especially on stage 5 with points) & you'll be fine.
