What's the dumbest thing you have done in college? - I missed exam because SLEEP

In 2nd sem , DSA paper .. I was studying all night and was very confident that I will nail the exam.

at 6 am , I thought let's take a nap and will wake up at 9 ( exam was at 10 30 to 1 )

alarm bhi lagaya , but phone charge nhi tha so it switched off

I slept and woke up at 11:20 , meri duniya hil gaii.. .5 min ke lie I was freezed..couldnt believe it.

I went outside hostel room and it was empty.. guard kehta " bhaiya aapka exam nahi hai kya"

Maine ye incident kbhi apne class walo ya parents ko nhi bataya .. unko bol dia I was vomiting blood.

Edit : As it was midsem , I didnt got a back ..as I got very good grades in endsem. Had to redo entire course for improvement though.
