- Let me know if you have any need of special accommodations before taking the test.
- Use a pencil (bring one or more sharpened and ready to go)! Also bring an eraser.
- If you miss the test, you will earn a zero (unless you have prior permission or
a clearly documented and incident of unforseen hardship such as illness or death in the family).
