Don't be so harsh on the TS, it's obviously not her fault.
1) Her first time and her instructor let her "play" around at a
roundabout? WTF
2) It's normal for learning drivers that are driving for the first
time on the road to be nervous and all
Quinsy, remember that the accelerator is sensitive, so be gentle
when you step on it. Few more lessons and you'll probably do fine,
good luck with your driving
