I don't find the content of bio an issue in HSC, I found other subs more content heavy. But I have a good memory and genuinely found at least the Yr 12 course interesting
For it to be my best subject, the amount of work didn't feel like work because of the pure enjoyment factor.
Blueprint was defs my fave, close with communication, then mab and then sfbh. (sfbh immuno part is great, it just has too many washy dotpoints)
That said, if I did the genetics option, that would have been my fave. The evolutionary option is pretty interesting as well.
