You are going to be fine, man
The following places will let you do engineering without methods:
RMIT (still requires you do Further)
Otherwise, you can enter a science degree at any university (UniMelb is excepted, because it requires methods), take the relevant maths unit, and then transfer into an engineering degree.
The following places will let you do commerce without maths at all:
La Trobe
Deakin
RMIT also has plenty of business degrees that are essentially the same thing, they just split them up by specialisation (so instead of studying all of commerce, you'll just study finance, or economics, or econometrics, or accounting, etc.)
Alternatively, you can do a Bachelor of Commerce at Monash by taking the Bachelor of Business offered at the Caulfield campus, doing the Clayton maths units to cover your maths pre-requisite (yes, you can do this), and then do a Bachelor of Commerce in your next year.
The following places offer pharmacy without methods:
RMIT (still requires further)
But also, the only other place in the state that offers it is Monash. However, you CAN do a bachelor of science and, if you take the right subjects (contact Monash for more information), transfer into the second year of a Bachelor of Pharmacy even though you didn't do the first year of it.
Also, this is me only considering 5 universities - RMIT, La Trobe, Deakin, Melbourne, and Monash. If you also consider VU, MIT, ACU, FU, etc., there are many more courses that may suit your needs. And, if you're willing to go overseas, the number increases AGAIN.
You can still do the courses you want, even without methods. And if there's a particular university you're set on that you HAVE to go to, you can always take an alternate pathway.
