i feel like I'll fail math boards..

(CBSE)Math exam went way worse for me, people were saying it's easy honestly, it was shit for me, was not able to manage time at all and worse of all, I don't think any of my question even is correct.. especially case study and 3 markers.. mcqs i checked, i got only 10 correct out of 20, I'm actually scared.. were there any seniors who was just like me.. how much were y'all expecting and how y'all got..
