Just took my science test

I got 2 out of 20 multiple-choice questions wrong, but the essay questions were super ambiguous... Still, I don't think they'll deduct more than 5 points. Physics and chemistry were the subjects I was least worried about because I studied ahead, so it's ironic that the 2 multiple-choice questions I got wrong were both from physics and chemistry... I was thinking that since Earth science seems to be the hardest for me, I'd make sure to get a perfect score on physics and chemistry to secure my gradeㅋㅋㅋㅋㅎ I don't know why I got one physics question wrong, and I'm really upset that I missed a chemistry question I actually knew the answer toㅠ I'll never forget the despair I felt the moment I realized I got it wrong, just 5 seconds after the end bell rang... This test was pretty easy, so I'm not sure about getting a 1st grade, but I hope I at least secured a solid 2nd grade..ㅠ I think I can salvage it in the finals, please let it be so..
