Is there any other topic in the a/a* grade area that you think might come up and is worth revising?

Hi. I'll attach a list I gave my students in the next post, but A/A* topics I would recommend looking at are

•

Bounds of a calculation

•

Simplifying algebraic fractions

•

Simultaneous equations (one linear, one quadratic/equation of a circle)

•

Sine/Cosine rule

•

Vectors

Here's a list of suggested topics that I gave my students last night.

I went through the non-calculator paper, noted which topic areas came up and came up with a list of other topic areas (there tend not to be repeats, so I wouldn't be expecting e.g. another transformation of graphs question).

Number

•

Some calculation where you are required to write down all of the digits on your calculator.
HINT: Remember the BIDMAS rule for those not using the fx-83ES or higher model Casio calculators.

•

Percentages

•

Reverse percentages

•

Simple and compound interest

•

Upper and lower bounds

•

If the question is later in the paper, it may involve working out the upper / lower bound of a calculation.

Algebra

•

3-D coordinates

•

Direct and inverse proportion

•

Graphs

•

Linear (y = mx + c)

•

Drawing the graph where the equation is given

•

Working out the equation of a line parallel to a given line

•

Working out the equation of a line perpendicular to a given line

•

Curves

•

Drawing the graph where the equation is given
HINT: Use TABLE mode (MODE + 3) on the fx- calculators

•

Simplifying an algebraic fraction, e.g. (x²-5x+6)/(x²-9)
(factorise the numerator, denominator, then cancel down)

•

Simultaneous equations
(either two linear, or one linear and one curve)

•

Trial and improvement

Geometry and measures

•

Bearings (often with trigonometry)

•

Construction

•

Similar shapes and solids

•

Trigonometry (SOHCAHTOA, sine rule, cosine rule)

•

Vectors

Handling data

•

Estimate of the mean

•

Histograms

I don't any transformations or stuff like that will come up. Maybe boxplots?

Worth a look. Stem and leaf and cumulative frequency were on the non-calculator paper, so I would suspect a comparison of two boxplots for two sets of data (possibly with one of them having to be constructed with the quartiles, lowest and highest value).

Tip for comparing two box plots:

One measure of average, e.g. compare medians, then interpret the result in the context of the question.

One measure of spread, e.g. compare the range or interquartile range then interpret the result in the context of the question.

i think trigonometry graphs could come up

Thanks for this.

For handling data, I'll also add stratified sampling.

Are there any topics that cannot come up on paper 2 or are all topics able to come up on paper 2?

Personally, I don't think that things tested in a bit of detail on Paper 1 are likely to appear again on Paper 2. So, e.g. I would not be expecting to see another probability tree diagram, or transformation of graphs question.

There wasn't any probability tree questions. At least, I think not.

How accurate are maths watch predictions? I think I should probably revise all topic in all cases.

Hi. A tree diagram could be used for the infamous sweets question, although only one branch would be needed.

The MathsWatch list further up is a very long list. It seems to cover pretty much the whole specification, which is partly why I posted my summary that I gave to my students.
