I can say that doing two year twelve subjects, I am NOT neglecting Chemistry, English or Math Methods. Physics I'm sort of neglecting but at the moment I'm doing really well because I understand the topics in class that are discussed. Its just that in terms of studying for the tests/assessments, its definitely not the same time I dedicate for Biol or Further Maths. I usually study the night before the assessments and still manage to pull 85+, which for the moment, I'm happy with for my 1+2s. However, I put in about a week+ worth of work in preparation for a Biology of Further Mathematics SAC, simply because of the difference of significance/importance of marks.
I really am loving Biology + Further Maths, and so I think that I'm trying to go all out to try and obtain the best possible marks. As for my year 11 subjects, I LOVE them ALL!! Especially English and Mathematical Methods!
