Thanks all for the good advice. I should have realised that combination of good teaching and consolidation would stand me in good stead.
As was said, Saturday was going to be a possible day (today) and so it turned out to be.
Skills test completed and passed - so I needn't have worried - except that, as a musician, if I'm NOT worried about a performance, then it probably won't be very good, so a certain amount of apprehension and care is probably good in flying, too.
Thanks everyone!
