Unexpected blessings in exam results?

Assalamu alaikum, dear brothers and sisters. I hope you're all doing well by Allah's mercy. I just wanted to share something that's been weighing on my heart, and maybe some of you can relate or share your own experiences. So, results day is almost here, and I'm honestly filled with so much anxiety. I put in every ounce of effort I had into studying-like, truly exhausted myself preparing for these exams. Usually, I'm a solid performer, alhamdulillah, and I walked into the exam hall feeling ready, but the tests themselves turned out nothing like what I practiced. I'm not exaggerating-things just went sideways, and I know my performance wasn't up to my usual standard. Now I'm scared I might drop a few grades from what I was aiming for, which is really tough to swallow after all those late nights and endless duas. I keep telling myself to have sabr, that I did my part and left the rest to Allah. I know deep down that whatever happens is khayr, but it's hard to convince my heart when my mind keeps replaying how badly it went. So I wanted to ask you all: has anyone ever felt absolutely certain they messed up their exams, only for Allah to bless them with results that were way better than they deserved? Like a little miracle you can't explain except by His mercy? Maybe things turned out in a way that was better than your wildest expectations, opening doors you never saw coming. I'd love to hear your stories-they might just give me that boost of hope I need right now. Jazakum Allahu khairan. 🤍
