Koala4444 hey there, you’ll have to speak to your year level or vce coordinator for that. 🙂
If you’re in year 10 going to year 11, it’s entirely possible to do a year 12 subject in year 11 without doing it the year before. And then you can do 5 subjects in year 12 which is an overall 6 subjects. Whether or not you’ll be able to do this depends on your school, because schools will have different grade requirements/thresholds for accelerated subjects.
If you’re in year 11 going to year 12, it’s also possible for you to do 6 subjects in year 12. The only problem is that most schools consider this too much work and might not allow it. But there are exceptions.
Again, speak with whoever is in charge at your school so you can find out what they think.
Good luck!
