Focus on time management and answering questions swiftly. What recorces are you using to prepare? Your DM is a decent score, I’d really work on your technique for the other sections, you’ve got a week so it should be alright.
About a week before the exam I also got the Kaplan book which helped me with my technique in VR. Basically what I did was skim read the questions for key words that will likely appear in the text, then look for them in the text for the answer. This helped me a lot to improve my VR.
Are you spending too much time on each question I think? And for AR you need to look for a set of qualities the shapes/objects may have to give you the answer, this is where I recommend reading through the introduction to each section again to whatever preparation book you have.
