I passed my test about 2 months ago.

Practice your slow speed control (especially U-turn) and make sure you can do nice tight and clean turns without running wide and that you get good road position before turning.

You should be doing your looks and lifesavers everywhere you need to without fail and generally looking in your mirrors every 5 seconds or so.

One tip if you find signaling while slipping the clutch difficult on roundabouts (I found it hard to reach the signal button while slipping the clutch) is to do the roundabout in 1st not second....just a little slower and no need to slip the clutch making it easier. You can change up as soon as you can afterwards!

Other than that relax and try to enjoy the ride and good luck!
