What is natural selection? (Kinda looking for the perfect 1 line definition but idk if its possible lol)
Natural selection is the process by which the environment directly acts on the phenotype of organisms often choosing the most fittest in its environment and allowing it to pass on its traits.
Careful with how you word this - you've made it sound like an active process by saying "choosing". Would be better to say that the fittest organisms are able to survive or something like that.
Apart from practice exams and questions, is there any other effective ways to prepare for the final end of year exam ? I know they run revision lectures and are they effective and worthwhile? Much thanks
I found revision lectures worthwhile, obviously they're not long enough to really go into depth with all the content but they are useful for going over all the content briefly, and that can often be enough to remind you of topics you might have completely forgotten and can help with figuring out where to focus your revision.
I drew a lot of diagrams and brief notes to revise, e.g. a page for each point of the study design where I'd just draw/write everything I could remember about that topic and how it related to each other and I think that helped. There's some guides from past students
here that might give you some new ideas for how to study too.
For Biology what is everyone's best method to study effectively? (flashcards, rote, mindmaps etc ??)
It's going to depend on what works best for you. I think rote learning would be a waste of time because you won't get those sorts of questions in the exam, it's going to be more about applying your understanding so memorising a bunch of definitions won't help. I never really used flashcards, but I did use mindmaps and liked them.
Do i have to print out the million past VCAA exams i want to do or can i get ones from my school or VCAA? (I really dont wanna print out 5 past exams for $55)
As erutepa said, you can try asking your teachers, if that doesn't work printing at officeworks is about 10c a page I believe (which would make it about $4 per exam).
