  Sometimes its bizarre, i think wow i did really well in that test and i did rubbish and sometimes i find something really hard and i did better than i thought! I don’t think there is really a good answer but it must be that you are putting the right sort of answers down!

  It could be you study more for physics because you think it is harder so that you do better? Try to study chemistry and biology as much as physics, all three subjects are fun but tough.

  I think you were more self-confident about biology and chemistry and did not study enough, while because you find physics difficult so you studied it more. So, try to study all your subjects very well and practice answering exam questions
