Question

today is my exam on institution .there is negative marking what should i do

Answer 1

Don't answer a question about which you are not sure.Whichever important parts u r learning just learn them thoroughly instead of half heartedly learning everything.You won't write wrong in this way and this will avoid negative markings.Avoid cheating bcoz u never know whether ur frnz are writing correct answers or not.
Be patient throughout ur exam.
Hope it helps:)

Answer 2

that is very good for you and keep calm while giving examination.Don't leave any question if by chance you don't know the question guess it and then tick because there is no negative marking
BEST of LUCK
for your exam
