i wouldn't necessarily say that ezz.. yes, there is a connection between physics and maths, and i dare say that:
physics/2 = maths
but.. that's not the case in the HSC, we are required to write more than calculations.. usually the questions that require you to calculate things are before question 20 (not always
).. it really depends on whether you want to put the effort in it or not.. many people know they can't do something and that they want to do it, but the problem is they never work for it
and.. i think you can do it even if you are not so good at maths, of course more maths would help, but i'm sure it's a course for everyone who are capable of understanding the concepts and applicaitions of science, you can pick up on maths (mind you, you get a formula sheet in the HSC)
