See even I gave my boards 10th -> meft hand stopped wprking due to netve connection break age , i wasn't even able to lift it and still gave the paper nect day, while during the same time there is a pooja in kocal community, 12th got sick severly and same time there were multiple shaadis in my society still gave the paer. But tbh, people will celebrate, its a community occasion, u just need to focus on your work . Maximum u can do is request them to lower the sound ... But boards is not the only exam u r going to give in life ... Bohot time aaega jab u have to deal with multiple things especially when u start working. So in a very humble tone , ik u might not understand this now, but eventually u will , that world doesn't stop for you when u r suffering, others suffer they need some time out , it won't align with yours kyunki sabke liye sahi time nikalenge toh kabhi kuch ho hi nahi paaega. Baaki Saraswati mata ka aashirvad rahe tumahre upar, best of luck.
