If I were you, I would put away all study texts and open your revision kit / exam kit
Get stuck into that for as many mcqs as you can do as often as you can do them (don’t write your attempts within the book – write them on a separate piece of paper)
Listen to / watch the lecture videos and start trying the longer form questions after you have watched sufficient videos
A 2013 revision kit is probably a little too out of date so I recommend that you invest (not expense) a newer version
But don’t, please don’t, spend money on a study text
