Why would this affect you? If that's want you want and you want a high atar, don't worry about practical subjects. My school doesn't offer any practical subjects in year 11 and 12 and we do fine.
^ wtf? you're not allowed to do Standard at our school unless you absolutely fail yr 11 advanced.
Our trials are next week. We only found that out today. Just goes to show how much our school cares about the SC :]
