im not in vce rn, but i do have a rough understanding for majority of the subjects
if you enjoy the 3 sciences, go for it! you js need a good memory cuz for chem and bio u gotta remember a lot. tbh physics is js science-related-slightly-easier-methods.
u also gotta keep in mind science subjects (like phys) requires a lot of effort but doesnt scale as high as others
in yr 12 u can drop englang (if u feel like its taking too much of your time to focus on other subjects or is too challenging)
dropping methods would be pretty bad, tho its not a prereq in bach or doc of med in monash
you should focus more on chem and bio if you are trynna do medicine in uni, as phys is mostly for engineering-related career pathways
ofc, im not an expert at vce stuff nor am i even starting vce this year, but hopefully this helped 🙂
