When I wrote the exams I was pretty confident but for some like English (predicted a 94), ICT (predicted a 94) and Mathematics (predicted a 98-100) I knew I had missed by a slight margin. Grade thresholds confirmed this but honestly I had though I had gotten 2 As in ICT and English, but God saved me and I Gucci-clutched it. What is to be will be, you can't change anything by fretting. But you can try praying.
