1. People won't do your homework but act on the principle of helping to help yourself.
2. First aid: follow closely the given instructions.
3. Whenever you encounter problems, don't hesitate to ask. Try to describe the problem as detailed as possible. The more detailed, the better your chance to get an useful answer.
