im a fossil but here's my 2 cents anyway , I got 93 in bio***(for creds or whatever)
I can't relate to the teacher thing bcz my biology teacher was exceptional but even then bio takes a lot of independent study
do you use a textbook or provided with notes or resources in class? I would recommend using these to make your own notes for every module, defining each syllabus outcome and having notes under each, include lots of diagrams, flowcharts etc. since much of bio can be understood and simplified through visuals
use YouTube vids to supplement your understanding of things bcz some concepts are a bit complicated at first,like protein synthesis
once I had my main notes completed near trials I would revise them e.g. teach a friend something, read a section then write down from memory what I can recall etc. near HSC I made mind maps like one A4 or A3 page for each module which worked as good summaries, I recommend mind maps for any subject rlly
finally lots of past paper Q's with feedback from your teacher or peers
gl with finding a tutor ik rates are a major deterring factor, not sure how you are as a student but if you lock in and have a plan on how you'll study then u won't need tutoring imo cheers
