9:15 is probably the best time to do it,
An Examiner has 4-5 routes they mainly use during a driving test, and to properly test your ability they will want to avoid the main roads and being stuck in traffic for the whole test, this then eliminates some of the routes, i would not be surprised if you are kept on back roads,
I was kept on back roads and the instructor could not find a proper space for me to do reverse parking so i only did one manouver in my test!!
Best of Luck i am sure you will be fine
