**Teacher’s Speak:** Most students lose significant marks in maths exam due to silly mistakes, i.e. simple calculation errors. Usually these happen due to hurriedly doing rough work, or missing out signs (+,-), or not understanding one’s own handwriting while copying from rough work to answer. To avoid this, always patiently copy values from question paper to answer sheet, do rough work neatly, and cross check answers before writing!
