General advice on how to answer exam questions:
1. You can answer the questions in any order. Be sure to write the question number clearly though. You can use the front page for outline.
2. You should write one page for each question. Even if you do not use up one page, just leave some space so you can always come back to improve your answer. The remaining pages you do not use is just a waste of paper.
3. Each question is worth 5 points. Some questions are more difficult than others, but you should treat them all with equal importance. Finish answering the easy questions first and then spend your remaining time on the more difficult questions.
4. Try to answer every question. Do not leave anything blank. You might get lucky and receive 1 or 2 points.
