This is what i wrote in a similar question prior to recieving my psych study score

now that i have finished i back up my own advice 100%. Most of all enjoy the subject! its great and goodluck for this year!!

Don't bother about the learning activities in the Grivas textbook, here is why.
1)they are merely there for you to recite information in the text (copy and paste questions)
2)they do not cover any of the tricks that vcaa often throw in.
3)complete waste of time, boring as hell and you get so much value out of doing exam type questions.
second piece of advice!
When it comes to pysch, don't 'learn' the information, 'know' the information. Be able to make links between different concpets, and often think about why the information occurs, it helps you understand it.
third piece of advice!
Checkpointscheckpointscheckpointscheckpointscheckpointscheckpointscheckpoints. I will not emphasise enough how useful this small book can be. Full of the questions you should be answering. It gets to the stage where you have done so many questions in the checkpoints book, that you face the exam, read the first line and know what the question wants. Most questions are quite similar across the board of VCAA exams. I really recommend this book as it helps consolidate the information in your brain.
Personally i find notes a little hopeless (thats me) because i write them without making them stick and the most important thing whilst doing them is making sure they are colour coded haha. INSTEAD what i did, was identify the concepts that i found hard. wrote them on a piece of paper, read over the relevant extract in the text, and link them like a cause and effect map. What information is realted? ect... a mind map! that helped me, although i may learn differently to you
I also went to two lectures mid and end of year. I went to the NEAP ones. I found it quite valuable because it covered all the topics, and refreashed what i had learnt. Also i obtained a wealth of succesful support material that assisted me alongside checkpoints. Defs worth it, if you can afford it they are a bit pricy unfortunately
Make sure you enjoy the subject the content is great and really grabs ones interest. Although i have to say it is beneficial to have done biology, because it gives you a one up on the neural basis of pyschology but its not that hard. Anyway i have heard the study design has been modifed anyway, cutting out some of the complicated material
One last piece of advice Learn the core! not the superficial 'classification' eg.. waffle information. you have to UNDERSTAND it
Good luck, hope this helps and enjoy year 12 next year!
