URGENT parents threatening to marry me off if i dont score well in jee mains

(tldr: need 97%ile, scored 89%ile in jan attempt) i am not able to think straight after what happened today, for context I am an only child in a low income household and my parents joined me in a dummy caoching since it was cheaper and near to my house and many of my cousins go there I got around 89%ile in first attempt (around 110 marks 50P, 35C, 25M), idk if it was due to the exam centre pressure or something like that since i was getting 180+ in mocks the day the results came all hell broke loose in my house and my parents threatened to marry me off if I dont do well in second attempt for girls in my community its the only choice since private clgs are too expensive for us I just need 97%ile for good gftis, and looking at jan attempt cut offs its around 140 marks, can someone guide me on how to increase to that
