After analysing Paper 1 of the Edexcel (1MA0/1f) Linear – Higher tier GCSE Maths exam on 11th June 2013, here is a list of topics which have not yet been tested and are worth revising over the next few days.

Here goes:

- Questionnaires and Surveys
- Frequency polygon
- Pie Charts
- Scatter Graphs
- Conversion Graphs

- Mean / Average
- Median Averages and range questions
- Mode from frequency tables
- Range

- Experimental probability and predicting outcomes
- listing outcomes

- Angles on parallel lines
**(here is a good link)** - Angles in Polygons (interior and exterior)
- Constructions – triangles / quadrilaterals with protractors and or compasses
- Loci
- Circle Theorems

- Area calculations compound shapes
- Area and Circumference of circles
- For circles remember: Area = π r
^{2 }Circumference = 2 π r or π d - Arc length
- Sector Area
- Surface area of prisms
- Volume of cones and frustrums (use the formula sheet)
- Volume of Spheres (use the formula sheet)
- Reflection
- Enlargement using scale factor(negative or fractional) with a centre of enlargement
- Similar shapes ( When one shape is an enlargement of the other they are similar)
- Congruent shapes (Shapes which are identical)
- Mid points of lines using coordinates

- Simplifying expressions
- Solving quadratics by factorising or using the quadratic formula. Using solutions to sketch graphs.
- Factorising expressions
- Substituting into formulae
- Trial and improvement
- Plotting quadratic graphs by completing a table of results
- Inequalities (Regions on a graph)

- Fraction calculations
**(use the fraction button on your calculator)** - Fractions of an amount
- Adding and Subtracting Fractions
- Multiplying and dividing fractions
- Equivalence: fractions, decimals and percentage.
- Ratio: equivalence and dividing by a ratio
- Proportion problems (Typically recipe questions eg. 100g of flour for 5 cakes how much flour would you need for 10, 20 etc)
- Rounding to decimal places and significant places
- Converting between currencies (The past few papers have included word problems for this eg. sunglasses cost £70 in the UK and $90 in the US which are the cheapest if £1 = $1.20 )
- Compound interest
- Percentage increase or decrease.
- Surds – rationalising the denominator

This is not an exhaustive list, however the topics in the list were not tested in Paper 1 on Tuesday.** Good luck to all** with the final preparation and of course the exam on Friday.
