Have you worked through all the mini exercises at the back of the course notes? Have you followed all the worked examples of past exam questions? Have you listened to all the F7 lectures on site?
Have you ever written in before asking for help on some matter that you haven’t fully understood?
Well, have you?
Try doing all of the above – throw away your study text (well, at least put it on one side to be used for reference on those really odd occasions when you totally do not understand anything from one of the video recordings)
And practice, practice, practice past exam questions
