**Tips for IGCSE Additional Mathematics Examinations**

**Integration:**Do not leave out the arbitrary constant ā+cā after integrating an expression.**Differentiation & Integration:**Do not get confused while differentiating and integrating š ššš„ and ššš š„.**Logarithms:**There is no negative values in*log*and*In*expressions.**Quadratic:**Be aware of inequalities sign errors while deriving critical values of the quadratic equation.**Trigonometry:**Read the question carefully if they require you to answer in radians or degree form.**Trigonometry:**Make sure all values of all relevant quadrants are calculated.**Circular Measure:**More digits in the previous value should be used to calculate the answer for the following sub-question.**Circular Measure:**All angles must be in radian form.**Relative Velocity:**All angles must be in degree form.**Indices:**Indices with brackets should be multiplied, while indices without brackets should be added. For instance: (2^{3})^{2}= 2^{6}, 2^{3}x 2^{2}= 2^{5}- Always type in the correct values in the calculator.
- Look at the marks before answering the question to check how much working should be done.
- Be aware of sign errors (negative sign, positive signs)
- Remember to show sufficient amount of working.
- Do not get confused whether to apply permutation (order matters) or combination (order does not matter) in different questions, do more practices.
- Make sure that you are working to the required level of accuracy and give your final answers to the form required (Angles: 1 decimal place, Other values: 3 significant figures).
- Remember to use the given answer in the previous part of the question.
- Do not leave the answer in terms of š¦ rather than completing the solution for š„.
- Use the given substitution.
- If you run out of room for working on a question, request for an extra piece of paper which can be then attached to your exam booklet.

**Before the Exam**

- Prepare suitable equipment to be brought into the exam hall (e.g. scientific calculator and geometry set)
- Check your exam timetable to plan your revision.
- Find out the structure and the format of the question paper.
- Look at past examination papers and be sure what they expect in an examination.
- Make revision notes.
- Practice drawing clear, simple, neat, fully-labelled mathematical diagrams and graphs.
- Work for short period of time then have a break.
- Revise small sections of the syllabus at a time.
- Make sure that you show all the necessary working when practicing questions
- Make sure that your answers are in the correct form when practicing questions.
- Look at mark schemes to help you to understand how the marks are awarded for each question

**During the Exam**

- Read the instructions carefully and attempt to answer all questions.
- Plan your time according to the marks for each question. For example, a question one mark requires less time and a shorter answer than one worth 5 marks.
- Do not leave out questions or parts of questions. Remember, no answer means no mark.
- Read each question very carefully.
- Identify the command words ā you could underline or highlight them.
- Identify the other key words and perhaps underline them too.
- Try to put the question into your own words to understand what it is really asking.
- Read all parts of a question before starting your answer. Think carefully about what is needed for each part. You will not need to repeat material.
- Look very carefully at the resource material you are given.
- Read the title, key, axes of graphs, etc. to find out exactly what it is showing you.
- Look for dates, scale, and location.
- Try using coloured pencils or pens to pick out anything that the question asks you about.
- Answer the question that is being asked. This is very important!
- Use your knowledge and understanding.
- Do not just write all you know, only write what is needed to answer the question.
- Plan your answers. Clear, concise, well-ordered, well-argued, well-supported answers are necessary.
- Annotated diagrams can help you, and be used to support your answer. Use them whenever possible to help you visualise the information given if a diagram is not provided in the question.
- Make sure your writing is clear and easy to read. It is no good writing a brilliant answer if the examiner cannot read it!
