Why I Did Not Do My Corrections

I am sorry that i did not do my corrections. When Evelyn return me my math work book i wanted to check for corrections but Wei How was rushing me to hand in the math work book as Mr Wan said that if the group hand in the math work after the bell rang you would deduct 100 points from the group. But i wanted to check my work book but before i flip to the page where i had corrections the bell had already rang so i just hand the book up to Wei How. i am really sorry and i promised that i will check all my work for corrections before i hand up to you.
