Mathematics is seen as a key skill at Ashbourne College and the department is fully resourced with an incredible teaching team. Specialist staff teach each strand of the course: physicists teach our students the mechanics modules; statisticians and ex-city workers teach Statistics; computer scientists teach the Decision Maths and pure mathematicians teach the Core Maths modules. This has led to consistently outstanding results with 80% of our students achieving A grades and 60% going onto achieve A grades at Further Maths.

## Why study Mathematics?

Mathematics is the bedrock of nearly all science and economic-based disciplines, from physicists and geographers to bankers and engineers. A student should always consider taking Mathematics to at least AS level to prove to future employers that they are comfortable dealing with many different types of figures and calculations.

## Which syllabus do we follow?

We follow Edexcel specification for Mathematics.

## How many units are there?

There are six units in total. Mathematics works in a different way to most other A levels. All students must obtain the four Core Mathematics modules listed below. Ordinarily they will study for and sit C1 and C2 in the AS year and C3 and C4 in the A2 year. Students must also study for and sit two additional units. These could be both from the same area, for example S1 and S2, or from two different areas, for example S1 and M1.

## What is each unit about?

### Core Mathematics

^{10}. This develops further in C3, the next module. After that you will extend your understanding of Calculus and learn how to prove things such as: if you are given a certain length of fencing the maximum rectangular area you can enclose is a square. These problems involving maximum and minimum values are interesting and challenging.

You will take your understanding of circles from GCSE a little further and learn about a different way to measure angles called Radians – very important. In addition to lines and parabolas, you will also add another equation to your arsenal. Work on series continues with the Geometric variety. This actually is interesting and will introduce two crucial elements of Pure Mathematics: limits and infinity. With your understanding of an Infinite Geometric Series you have pretty well all you need to understand interest rates, the value of stocks and bonds and how to make a fortune in the City.

Leaving the most feared to last: Trigonometry. You will extend your understanding of sine, cosine and tangent so far that you will not recognize them and as a bonus get to know their graphs as well. There is a kind of new equation waiting for you (trig equations of course) which has been known to drive some students potty. To be fair, Trigonometry forms the basis for our understanding of so much in the world right up to Quantum Mechanics. So the next time you visit the recording studio and observe the sound engineer chilling at the soundboard, know that they are employing harmonic analysis which derives from Fourier analysis (after the late, great French mathematician) which is founded on trigonometric functions. Spinach is good for you and I am sure so is Trigonometry.

If you are a clever scientist you will see that the work on exponential functions is dominated by its application to rates of change. You may thus relate it to processes such as radioactive decay in physics, rates of reaction in chemistry and the growth of populations in biology. If you are really enthusiastic, you can use this study to introduce yourself to chaos theory!

### Mechanics

Principally, M1 is about elementary applications of Newton’s laws (how many?) but, more interestingly, it is about the mathematical model used in analysing the forces of nature. Understanding the model is challenging but, if taken a little further than A level, will give anyone an appreciation of why Aristotle was wrong in thinking that all bodies require a force to keep moving in a straight line (the law of inertia). Equally you should wonder at the genius of Galileo, then Newton, then Einstein in overturning the Greek’s idea. The struggle to understand the model in M1 schools students in the patience necessary to understand Einstein’s Special Theory of Relativity.

1. Practice makes perfect.

2. Proficiency in exams depends on speed; the faster you are the more likely will be the reward of your efforts an A*. Speed depends on pattern recognition; you should be able to identify each and every problem you encounter as a ‘type’ which you have met before. You should rarely have to think in an exam because you have done your thinking beforehand.

M2 also introduces two new topics: centres of mass and conservation of energy. Of course all of these are related to physics. Sadly, much as we would otherwise prefer, most human beings seem genetically wired to silo mentalities: energy in mathematics is somehow different from energy in physics (where there is any energy at all). Still hope springs eternal.

### Statistics

For example, suppose one person in 1000 actually has a particular disease. A pharmaceutical company develops a test which is 100% effective in identifying a disease; ie if you’ve got it, the technique will never fail to indicate that you’ve got it. Unfortunately, if you don’t have the disease, the test is wrong 1% of the time; ie even if you don’t have the disease, the test will say you’ve got it anyway one time in 100. You visit to your doctor’s surgery and test positive: what is the chance that you actually have the disease?

This example, of course, is a question in probability. There is an easy way to solve it and a hard way; and of course we teach you the hard way. The study of probability supplies you with an important way to understand risk. With little more than A level understanding of probability, it will certainly help you understand why Lehman Brothers’ bank collapsed as well as appreciating how careful you must be interpreting the results of trials for a new drug.

S1 also deals with the very important area of correlation and regression. If you have a good teacher (all at Ashbourne!) they will help you understand the true meaning of ‘regression to the mean’ and why correlation is not causation. An example of the latter is (ironically?): the more hours of private tuition students receives the worse their grades (negative correlation). Does this mean that teaching makes students stupid?

Finally S1 examines the analysis of data and will help you answer the following questions: 1. If Bill Gates walks into a pub, what happens to the mean (average) income of the patrons there? What happens to the modal income? Importantly it also deals with the concept of variance or standard deviation, both of which are used by financial boffins to measure risk and volatility in the markets. In fact they will even sell you volatility if you have the appetite!

P.S. You also get to learn quite a bit about bell (normal) distributions which apply to many things like IQs, exam results etc, but regrettably for bankers and the rest of us, not others like the price of shares and derivatives.

This idea leads naturally to the topics of confidence intervals and hypothesis testing which are fundamental for psychologists, economists and doctors.

In S2 Mathematics you will also meet two very important distributions, namely the Poisson and Binomial. These are both extremely useful. For example, the Poisson arose from observing the number of officers in the Prussian cavalry in the nineteenth century who died each year because they were kicked by their horse. If someday you are bored waiting for your bus you might amuse yourself by counting the number of buses (not yours) that arrive at the bus stop each minute. More or less this illustrates a Poisson distribution.

Finally you will apply your knowledge of calculus to continuous distributions.

This module is not dense but is conceptually quite challenging. I suppose it indicates a general principle: in applied maths once you establish a rock solid understanding of the fundamental first principles you should have little difficulty afterwards.

### Decision mathematics

## How is each unit examined?

All examinations last 1 hour and 30 minutes and have 75 marks. C1 is a non-calculator paper. Students can use calculators in all the other papers.

## How is the course structured?

AS students will study for C1 between September and December of the AS year, with a view to taking the C1 examination in January. They will then begin studying for C2 with a view to taking the C2 examination in June. Students also study for M1 and S1. In the A2 year students will begin studying for C3 between September and December with a view to taking the exam in January. They will then begin studying for C4. Student may continue with S1 and M1, alternatively they may study for S2, M2 or D1 and D2. To gain an A level all students must sit all four Core Mathematics modules and two further modules.

## When do the exams take place?

Students sit C1 in January and the remainder of the AS units in the May/June examination period. There will be opportunities to resit AS units or sit C3 in January of the A2 year. The remaining units will be sat in May/June of the A2 year.

## Beyond A level for Mathematics and Further Mathematics

After studying Maths and Further Maths many of our students have chosen to read degrees in Engineering, Physics, Economics, Accountancy and Pure Mathematics. Our students have gone on to study both in London at the prestigious University College London and Imperial College London and further afield with many students being placed at Warwick, Nottingham and Cambridge.

## Any other information

Students intending to study Mathematics at AS and A2 level should ideally possess A*, A or B at GCSE. However, it is possible for a student with a grade C at intermediate level to be successful in their study of A level Mathematics.

Mathematics at AS and A2 level is both challenging and demanding. It is fundamentally different from the study of Mathematics at GCSE requiring strong skills in algebraic manipulation and a disciplined approach to study. Success is achieved by students who adopt a consistent work pattern. Students who have a tendency to ‘cram’ at the last minute may find this strategy unsuccessful in this subject.
