Every subject scales up and scales down depending on how you go. As for Legal yeah it doesnt scale as well as chem or physics or eco. BUT if u do really good in it then ofcourse u will be scaled well.
haha yeh economics... dont let anyone tell you it scales really well.
i got 63% in ec history and 75 in eco for my hsc and history was counted.... my eco was a complete waste of time... unless you are super good at eco's then its worthless
