Exam problem / computational question
Problem and computational questions require you to perform some calculations to provide the answer. Sometimes you may be required to use multiple calculations to arrive at an answer.
Preparation
- Practice is the key to success.
- Know the formulae, theories, and key terms, and when and how to use them.
- Practise steps in solution methods.
- Practise using equations in as many ways as possible.
- Work through problems in texts and old exam papers, using them to identify your weaknesses.
- The revision strategy here is to build working knowledge: a familiarity with adaptive techniques to solve a range of problems.
- Rote learning is usually not very helpful.
Strategies for answering questions
- Write down relevant formulae, equations, and rules.
- Clearly show the steps you have taken in working out the answers.
- If necessary (and appropriate) write some notes to explain your answers.
- For numerical problems involving computation, make sure you include the appropriate units (e.g. ml, km, m/sec, etc.) in your final answer. Underline your final answer, as it will help with clarity.
- Go through and solve the easier problems first and return to the more difficult ones later.
