CFA level 3 mocks - Advice needed

Hey all, can someone suggest me how you felt the actual exams was when compared to cfai mocks? I am a re-taker and failed by 1 question. Mock scores previously were between 60-65 on kaplan and 65 on M1 and 70 on M2 cfai mocks. I felt the actual exam to be way more different and difficult than any of the mocks i gave. Started with cfai mock again and scored 70% today. How should i approach with 40 days remaining?
