Make sure on the first few questions (1-2 marks) you don't waste too much time. These questions really don't require much explanation (techniques wise) so don't write out a whole essay. Just give a decent explanation linking your chosen examples to the given question.
With the longer questions (3-5 marks) try picking out examples which you feel you might be able to write a lot about - having fewer, more detailed explanations is better than having multiple weak explanations. For questions which ask you to relate to multiple texts, reuse your examples from other questions, and simply shift your explanations to fit the question. <–– because of this I recommend starting from beginning to end
Pick out examples that stand out to you first, then write as much as you can - but make sure it all relates to the question. This will help you start off with a decent pace. If you feel like you're ever slowing down or if you have nothing to write, just move on to the next question or try adding to earlier answers - this could help you think of something to write for the question that you're stuck on.
It also pays well to make connections to other parts of the rubric, other than what is stated in the question - this is more awarded in later questions but try to weave it in all your answers, this is to show your understanding of the rubric
It should come to you after you do a few more papers - just keep practising and you should get the hang of it. Good luck!
