"completing the book" ,does this mean doing each sum of each exercise. In 8-9 days did u all completed whole book?

Do we have to do all reflection sums on graph ppr or directly write ans on answer sheet... When it is not specified in the ques ppr

Tip :-
Redraw the geometry and mensuration figures (if u want 80)
in sums of algebra where unknown quantities are needed to be found out , after finding the value substitute and cross-check
avoid commercial maths sums
don't forget to write the scale and ques no on your graph paper....
will post more later
