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.
- 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.
