In preparation for the exams I've printed VCAA exams for the years (2017,16,15,14,13 ,10) exams 1/2, I've stopped doing checkpoint questions since they're essentially VCAA exam questions compiled in a book. I've then proceeded to do them under exam conditions and found out that I could finish exam 1 with (25-30min) left on the clock and couldn't finish exam 2 as I tend to overthink the questions and waste time. This lead me to make quite a lot of mistakes but I've corrected my mistakes, taken a picture of the question and printed all my incorrect answers of the past exam papers I've printed to compile them in a log book. My question here is, is there an effective way for me to tackle my problem of overthinking and wasting precious time during exam conditions and do you think I can do anything else differently that could essentially help maximise my exam results and potentially get that 50.
