My second daughter does physics in an Aus school, she’s about to start the first term’s work for her final year (she’s also come top of her physics class, I’m proud 😀).
In her hard science cohort maths would be preferred over psychology, but because of the different way uni entry works. Stop reading here if you’re not interested in how another system works!
In Australia there are 3 different types of maths at pre uni level, general, methods and specialist. Specialist maths is really only for those you want to do maths/engineering or want a really good ATAR. I don’t think anyone is doing physics without maths but could be because they’re maximising their ATAR score.
Students finish the year with a ATAR score, rather than individual grades. Most students will do 5-6 subjects, then the ATAR takes the top 5 into consideration. Our largest local uni is competitive, so the scores required to get into really popular degrees are higher than others, I think nursing needs 80 something, which is higher than most. A basic BA needs 70, Bachelor of science 80, law is around 90.
Medicine’s official requirement is high 90s, but no one will get in without 99 point something, ie being in the top 1 percent. Academic scholarships are offered for some degrees for students with ATARs of 98-99, although I think to entice some bright children away from medicine and into other courses.
My daughter goes to an academic private school, in her year at least 5 should get in that top 1%. On this year’s grade prediction she’s sitting around 99.50 - all of her raw marks in her two maths and chem/physics are 95% or higher.
She’s not trying to get into medicine but of her cohort who are, they are deliberately choosing harder subjects that scale well. If you do well in a hard science, it scales up - an 80 in physics will scale up to around 86, an 80 in psychology will scale down to the low 70s. Some languages scale well, as does literature, philosophy and literature extension but generally academic children going for a competitive course would choose maths methods over psychology.
