I cant pull that off cause all my teachers know me .... tho examiners actually wait when i tell em ... "please mam i need to write like 1 line"
One paper had 2 sections. I was done with section 2 and had to write a few more lines of section 1. (im the 1st student in the class ie 1st row 1st bench) so i told him and the guy actually started collecting section 2 first
<3 Thanks for the extra 2 marks
