Flying Grading is designed to be a filter. Your final assessment is an opportunity for you to demonstrate your ability to learn. They are not looking for you to star.
I cannot comment on whether an opportunity to solo will present itself, but in my day it was not uncommon. Don Pugh authorised my first solo in WK634 on October 2, 1976. Earlier that day, the late Norman Lees went solo too.
Enjoy the process and your career. It certainly has been good to me.
