I recommend that you read study guide books, articles, and opinions from top students on the study methods they used. End of year 10 and prelim is the time you can really use to find a good study method that works for you. In your subjects you will most likely have to absorb a lot of information so try everything you can, and then maybe do practice papers to see which study method is the most effective in remembering information and understanding it. I dont have a student method for you just have my 2c.
