failing foundation math

just today after all the exams are over I checked quantitative aptitude paper's solutions on yt and found I'll be failing by freaking 2 marks. i wrote all other papers pretty good so i thought I'll be passing this attempt but this one paper is setting me back. (this was my 2nd attempt, i failed 1st attempt cuz I got really sick during exams) there might be somewhere that my mark calculations went wrong but that's just me being delusional. i was so happy for the whole day cuz economics paper went well and now this ruined my day. (rant end)
