Hew,
My test was booked for last Thursday, but the morning sortie (focussed on ILS's) didn't go well enough for me to be considered ready (although on previous trips another Instructor considered I was).
In the end, I know I wasn't up to the mark (the needles don't lie), and was quite cross with myself about it.
Will be doing a bit more practice, both in the air and on the MSFS, over the next few weeks, to try to get it sorted!
Thanks for asking!
Cheers
Wycombe
