LF WITH YOUR OWN CALCULATOR
BRING IT TO SCHOOL EVERY DAY
DON’T RELY ON THE SCHOOLS CALCULATOR WHICH MAY HAVE A DIFFERENT LOGIC SYSTEM TO YOURS.
If you are asked to measure a line and it measures 9.1cm use 9.1cm. Do not assume that the line is supposed to be 9cm long.
TRIAL AND IMPROVEMENT Usually there will be a table for you to write your attempts in. You do not need to fill in all the rows . You must have at least one trial above and one trial below the correct answer.
IGCSE数学考试注 意要点
EQUIPMENT: Most students bring all the correct equipment (Pens, Pencils, Ruler, Angle measurer/protractor, Calculator) However there is a lot of evidence which shows they simply don’t use it!
READ THE QUESTION:
It is recommended that you read the question TWICE.
There is plenty of time.
You can underline the important parts of a question if you wish to
UNITS
Even if not asked to always write down units at the end of a question
If a question contains mm and cm it Is a good idea to convert all to the same
DIAGRAMS: Almost all diagrams are NOT drawn to scale. Many students ignore this fact. They simply measure angles and lines without calculating them and consequently get no marks.
MATHS SPECIFIC ERRORS
PROBABILITY
A very large number of answers are still given as 1 in 2 or 5 out of 1O. These are incorrect. Answers should be decimals, fractions or percentages.
METHODS: Working out MUST be shown.
There are a lot of method marks available and it is recommended that all relevant stages of working are shown.
Incorrect answer and no working gains no marks If correct working is shown and a careless error results in an incorrect answer you could gain 4 out of 5 marks available
CALCULATORS Make sure you can read a display that is in Standard Form. No credit is given for writing an answer as 1.6306. Make sure your calculator is set in the DEG mode
As a general rule if the question uses fractions then give your answer as a fraction.
Reminder:
A probability answer cannot be greater than 1!
UNITS You will have to give your own units for at least one question. Units of length, volume and area are frequently mixed up by students. Learn them. Learn common Metric to Imperial conversions. e g 1 kg = 2.2 lbs, 1 mile = 1.6 Km. 1 Gallon = 4.55 Litres etc. Reminder: There are 52 weeks in a year.(Many students use 50)
ACCURACY Do not round answers off until the very last line of working. Use the calculator memory function and notation such as 16.534….. This is especially important in trigonometry questions. (There is a significant difference between 23x1 .66 and 23x1.66666666)
