Prediabetes

Hi, I have been told I'm prediabetes and my Desmond Appointment is not untill next month. My Blood Sugar is 7 day Ave 6.8. 14 day ave 6.5 and 30 day Ave 6.3, my question is what should I be aiming for. Thanks for any help. I should have mentioned that November last year my Blood Sugar was High 8s Low 9s that's what started all this.
