#Do not miss out on 'Drawing a table to represent data given'- type of questions, because they do not have any formulae, but only simple addition and subtraction; and since you are allowed a Calculator, it cannot be simpler.

#Concentrate also on frequency distribution sums. They usually carry more marks since they are graph-based. The universal law in graph problems is 'Writing SCALE' which we either forget or don't know to write. Write it in the top right corner of graph sheet.
Sample:
X-AXIS: 1 cm = 1 unit
Y-AXIS: 1 cm = 10 units

#If there is a need to show different regions in graph through different colors/shading methods, definitely give a legend/key indicating what each color/shade/stroke represents; preferably in the right side of the graph. Do not crowd your graph with numbers, units, etc. Give it as neatly as possible.

#Don't complicate your graph by making each centimetre represent 3, 4, 6, 8 units, etc. Always prefer units in 1, 2, 5, 10, 50, 100, 200, etc.

#Make sure you do not spend so much time on problems you have absolutely no clue. Even a shabby presentation may come in the way of getting full marks. Do not overwrite. Make it a neat table/graph as far as possible. Use the last sheet of your answer booklet to make rough calculations and make sure you strike them out.
