yes of course it is. 1 week is more than enough to memorise some quotes and develop your writing technique-
make sure you have a good structure in mind for your paragraphs and for top grades ensure you know your background info of the novels (Victorian era context etc)
try practising your timing by doing a a past paper or so, and also get your teacher to mark it and give you the harshest feedback.
and also aim for 9 always
good luckkk!
