I'm scared of tomorrow's exam results

My exam results would be out tomorrow and everyone expects me to get a 4.00 GPA while my calculation shows that I’m at a 3.75 GPA. My teacher messaged me to pray that I get a 4.00, my mom has bought me a very expensive gift, my friends have congratulated me in advance and I feel so pressured. I want to prepare a speech, choose the prettiest outfit, practice my makeup, make funny tiktok but it feels like I’m jinxing myself for failure if I do all that. The results would be out at 11:30 am but we’re expected to be at school at 10/11 am. I want to believe my teachers when they say I might have a chance to get a 4.00 but I’m so scared because of the uncertainty. Don’t get me wrong, a 3.75 GPA is a big achievement but it’s not enough to get into my desired university’s course since the merit is too high (they want 98% and I currently only have 93%). For once in my life, I want to be the best student because this is my last chance to shine in life as a high school student but honestly, it’s just to prove that I’m still smart.
