Its a sad sad situation

       I had my first maths topical test today. 7 questions on probability and progression. WTF!!! the paper was really easy!! and guess what? I failed to get 100% all because of my carelessness >.<
stupid enough of me to not use my calculator, its so depressing.
such an easy paper yet i still fail, more over i did with so much confident i’ll aced it. haiz…



again i remind my self of the digit 90
