This won't definitely work for everyone, for a particular subset of people it will probably be most effective but i thought I'd share it with you guys.
I used this strategy and it worked rather well for me.
Basically you do about 2-3 exams to start with, you correct them each individually and put a star next to every question you got wrong that wasn't due to an obviously silly mistake. Once you've done correcting the paper in its entirety you can move on to this next step. Go through the paper and look at each question you got wrong, find a category for it, "Organelles" or "Immune System" and write the category on the back page of the exam. Moving through the paper make a tally of each type of question you got wrong, like this:
Organelles - |||| |||
Immunity - |||
BioChem - |||
You can be even more specific perhaps and write things like humoral immunity and hopefully you guys won't get that many question's wrong but i think you get the gist of it.
Go back, read your notes, read your textbook, listen to a podcast, do whatever about that topic. You also know which area's you need to study the most in.
After you've read it, repeat with another exam and another exam and another exam...ect. Hopefully, you'll find, like i did that over time the things you write on the back gradually lessen and lessen as you learn more of the things you need to know. This will be one of the greatest proofs if this method works for you and its also pretty inspirational too!.
This is also a good way to study instead of reading through every little thing in the textbook. I consider it to be a rather efficient way of learning, especially for those of you who don't have a full grasp of everything in the course or who are short on time.
It worked for me and with exams coming up i just thought id share it with all you guys still going at VCE Biology and best of luck!
