Also don't forget the "second route" where even if you do your grades 5-11 in the second highest tier of school and then notice you still want to go to university, you can add 2-3 years of school, which is not that uncommon for people who seemed to be not up to the "higher education lane" at age 10-12, but are absolutely capable at age 16-18.
