Just back from my test with Dougie, the IAM examiner. And I got a "recommended for membership" which means I passed!
Points to work on were linking bends i.e. "apexing" and one or two opportunities for overtakes where I was a bit late or missed the opportunity.
A great milestone, and he said to keep going and improving by considering IAM Observing, Senior Observing or by thinking about working to a Rospa Gold grading.
Route to follow. I'm off to Vittoria's this evening to celebrate.
