Edexcel Paper 2 Worked Solutions Paper – Foundation (PDF)

**Higher:**

Using a calculator – make sure you show some working out at each stage to guarantee marks

Scatter graphs – always draw a LINE OF BEST FIT and show that you’ve used it

Estimating the Mean – midpoint x frequency, add them up, divide by total frequency

Best buys – involving percentages and/or fractions of amounts

Cost of energy bills – lots of people tipping this one

Plans/elevations

Bearings – if no diagram is drawn then sketch one clearly showing the angle you are trying to find. If you get the correct diagram you get a method mark.

Ratio – make sure you can do those that require you to write a ratio as well as when it is given

Exchange rates – you are either multiplying by the conversion or dividing. If you aren’t sure don’t do both otherwise you get zero marks.

HCF/LCM/product of primes – probably in context e.g. bus timetables but be good at formal method too

Sequences – finding the nth term, using it to show if a number is in that sequence, generating terms of a quadratic sequence

Trial and Improvement – part a might be a ‘show that’ question to explain where the equation has come from

Compound interest – could be comparing with simple interest, or depreciation e.g. with the value of a car.

Angles – include using parallel line angles and angles in polygons (interior and exterior)

Frequency polygons – plot at the middle of each group, join with ruler, DON’T join the start to the end, you lose a mark for this

Translations – probably describing as both on non-calc were drawing Qs

Draw a straight line graph or find the equation of a straight line graph

Enlargement – include fractional and negative scale factors just in case

Similar shapes – likely to be volume or area related, remember to write the enlargement scale factor first; area scale factor = scale factor squared, volume scale factor = scale factor cubed

Compound shapes – area and/or perimeter. Likely to include a part of a circle so remember the circle song.

Pythagoras’ Theorem – could be in context e.g. ladder problem (2 sides given, find the 3rd side)

Trigonometry – probably combined with Pythagoras so make sure you can spot which is which (angles given and find angle or missing side)

Histograms – always calculate the frequency density = frequency divided by class width. If asked about total frequency or to fill in table, area of each bar is the frequency (area of a rectangle so base x height)

Sine/cosine rule

Quadratics – expand two brackets, factorise, solve using the quadratic formula

Cumulative frequency – plot at the end of each group, smooth curve

Volume of sphere/cone/frustrum – could be a use of formula question or involve algebraic manipulation to ‘find r in terms of h’ type questions. Remember to check the formula sheet and substitute relevant information from the question

Proof – e.g. that the sum of two consecutive squares is…, or prove that an angle = … (so you need to give clear angle rules and explanations)

Transformations of graphs.

This is NOT a definitive list but my best guess about the main topics that will come up. Good luck on paper 2 everyone. If I have any further thoughts I’ll update over half term.

Best wishes,
