It could be extremely hard for you to come first in the yearlies given that rank unless there are like tiny difference in marks between your current rank and the person currently at 1. I think there is a possibility depending on your school policies, I personally did know someone who did the standard english course in year 11 but got moved up to advanced english in year 12 due to exceptional performance in the course. But this is very rare and dependent on the school's discretion, so it is best for you to not overthink about it and just concentrate on getting your best results at this moment in time.
