roll_over,
Do not be worried about the example above, the questions they will give you will envolve no decimal places, at most possibly 1, nothing like the above
I belive the CD's are 'essential' for the course, after the assesment (someone may correct me on that) But assuming that, if you revise, learn most subjects on the CD I don't see why you would have a problem with the assesment.
My advice is to practice quick maths, quick addition , subtraction, long division etc. Here is a list of the subjects for the START of the course, so the assesment isn't far from this:
MATHS
Algebraic Substitution
Simple equations
Subject of the formulae
Factorisation
Expand and simplify
Indices
Functions
The line
Travel graph
Numbers
Percentages
Areas and volumes
Pythagoras theory and trigonometry
Problems in bearings
Geometric terms
The circle
Vectors
Practice Mental Maths !!
Here is the Physics aswell:
PHYSICS
Mechanics
Work and power
Energy
Potential and kinetic
Input and output energy
Pressure - solid liquids and atmospheric
Principles of Hydraulics
Gears and cogs
Linear motion equations
Gradient
Distance time graph - Velocity time graphs
Force and momentum
Resultant force
Newton's Law
Forces
Mass, weight and density
Vectors and scalars
Center of gravity (moments and balance)
The turning effect of forces
The law of moments: levers
Parallel forces in equilibrium
Couples
Principles of gyros
Principles of piston and turbo jet engines
The Otto cycle (engines)
(You must be familiar with both Imperial and Metric units and be able to convert one to the other)
Sound
Longitudinal waves
Sound waves
Stationary waves
Optics
Sources and reflectors of light
Magnification
Reflection Laws
Refraction
Convex and concave
Magnifying glass
Dispersion
Heat
Heat and temperature
Internal energy
Temp scales: including Kelvin and converting temperature from one scale to another
Heating and cooling curves
Melting
Boiling
Evaporation
Gas pressure
Pressure and temperature of a gas
Volume and temperature of a gas
Volume and pressure of a gas
Expansion on matter
Heat transmission: - Conduction - Convection and radiation
Boyles, Charles and the General Gas Laws
Magnetism (Ideally you should understand the following but it is not essential)
Magnets
Theory of magnetism
Magnetic fields and neutral points
Magnetic effect of current through wire - coil and solenoid
Electromagnetic
Motor effect of current through a wire
The simple D.c motor
Electromagnetic induction in a straight wire - solenoid
Transformers
The transmission of electrical power
Fields and rule
Current electricity (Ideally you should understand the following but it is not essential)
Circuit components and diagram
Electric circuits
Potential Difference
Electrical resistance
Ohms law
Series parallel and mixed circuits
Heating effect of an electric current
Electrical power
Direct current and alternating current
The live, neutral and earth wires
Circuit Breakers, fuses and switches
Principles of electric generators
General
General outline of metals and materials commonly used in aircraft
The principles of aerodynamic lift
Cloud formation and general principles of meteorology
Confidence in handling numbers and ability in mental arithmetic
It seems like a lot, but once you get your head down, your see some of it fits in with eachother nicely. Considering I havn't done Physics in 10 years? And I did double Science, not Physics seperately at GCSE and got 13/15 it isn't as bad as it seems.
As for the maths, there will be a question on Pythagoras in your maths, so remember to cover that. Just practice mental maths, I can't say that enough. None of the questions are exactly hard but with the limited time, you really don't have time to spend on the easier questions as later on your need it! This is were I didn't do so great, double checking answers wasted time I needed later on.
