2. For each exam scenario, a recommended time and mark allocation are provided to help you manage your time.
3. If you are unclear about anything in the exam, ask the proctor for clarification. The exam proctor will attempt to clarify anything that may be ambiguous. Do not expect the proctor to provide other information during or after the exam.
4. Be sure to allow yourself some time to verify the correct operation of your solution.
5. Save your configuration often. Your exam mark will be based on your final configuration.
6. Relax and read each question very carefully. Be thorough in your solution but remember to pace yourself appropriately.
