For the reading and viewing part, the only practice you can do are past papers. So as many as possible so you can pollish your technique finding skills. Remember you also have to be able to relate it back to t he question. It's no use say ing this is a metaphor but not do anything with it.
If you want to prepare your creative writing your should have a plot/notes so you can adapt it to the question/stimulus. If not then you can prewrite 2+ different creative writings so you have a few that can adapt to different questions.
With the 4 essays, what you should do is make notes. In these notes you should write quotes, techniques, effect/mining and relate it back to the rubric. Do this for x amount of time for the different themes you want to approach.
Again, if you don't want to. Do this, me memorise 2+ different essays so you have different themes and quotes that you can easily relate back to the questions
In all, do as many practice papers as possible so you know what questions they can ask
