Hi there, and sorry for the late response,
I am also currently undertaking the VCE French course, thus do not have any 40-45 raw tips to relay, however, similar to roly and FinFin, my biggest tip for you, would probably be to immerse yourself in the language, as much as possible.
You may be struggling at the moment with reading and writing, but with time, this will inevitably improve.
The real challenge, is developing the more practice skills (i.e. listening and speaking).
Rather than seeking out native speakers, couldn't you just ask your teacher to meet up, one lunchtime per week, for a 5-10 conversation, fully in French?
If you have any questions that I may be able to answer, please feel free to ask!
P.S. Don't stress too much about only starting in Year 9, because before that point, it is mostly just learning different colours and animals (which aren't entirely relevant for VCE)
P.P.S Although a 45 raw would be fantastic, it is a significant achievement for anyone, (let alone someone who began learning in Year 9), so don't get too caught up in the numbers, and just try your best
