Ask them if you can take the test another time. Some professors expect you to show them a doctor's note explaining that you were too ill to go to class and take the test, so if you are really sick, make sure you go to Snow Health Center and get a note from the nurse or doctor who sees you. Call 911 from your phone. The people who answer are trained to talk with you and help you during an emergency and will also send an ambulance, fire trucks or police to your address, depending on what kind of emergency you have. Do NOT call this number if your situation is NOT an emergency.
Health insurance is really important for everybody.
Hopefully, you will never need it, but if you EVER need to see a doctor, health insurance will cover most, if not all, of the costs. International students are now required to have health insurance provided by the University unless they can prove that other insurance will cover their medical needs. This insurance is for your own protection. Information about the University health insurance was sent to you with your admission papers.
