Biochemistry is a second year uni subject, and it has both biology and chemistry at first year as prerequisites.Yes! Not only should they add extension bio, but add biochem too. I do both bio and chem and this would tremendously help me out. It would be like a chain
Bio helps —> biochem
Chem helps —> biochem
Bio chem helps both —> chem and biology
My subjects would just be 4unit bio, biochem, chem, English, math
I do know of cases where these have been waived for bio... that is, admitting a student with very strong first year chem into biochem without having studied biology... but never the other way around.
I don't see biochemistry as a subject appearing at HSC, though some biochemical content can be addressed in chemistry or biology or both.
