Guys I fcked up my chem paper

Ton main aaj subah 4 baje uthkar sab revise ek aur baar.. and exam dene gya... I remember at 11.15 jab mein exam likh rha tha.. sab signature vagera karke...muze ek mechanism yaad nhi aa rha tha jo maine kal raat padha rha tha.. isliye mein head down ho gya desk for 5 mins to remember that mechanism and bhai mein literally so gya.. I mean bhai esa kaise ho sakta hai.. I woke up 1.10.. vo bhi Kisika pad gir gya tab bhai.. 20 min mein bas 30-35 marks ka attempt kiya tha.. bohot dukh ho rha hai.. is there any solution?
