Okay, here are some things to take note:
1. Always, always, always label your questions. Which one did you answer?
2. Write legibly. Meaning: IT MUST BE READABLE BY A NORMAL HUMAN ADULT.
3. Don't use correction liquid i.e. Liquid Paper. That thing is sticky, messy and generally makes it harder to read your work (see point 2). No word out on correction tape, but if you know you always make mistakes, use one or cross out neatly.
