In general, I didn't felt doing the questions set by my teachers on analysing my texts were very helpful to assist my understanding, I find it much more useful for me to independently analyse the texts and write practice essays and gain feedback. Remember, no matter how many questions you answer correctly, they are likely to only be short answer responses, but in your exam, you need to write essays, and you will need to write practice essays to refine your essay writing skills. Make sure you prioritise what works for you, don't feel compelled to do every single piece of homework set by your teacher-because they will not be counted towards your final internal assessment mark.
