Nasty handwriting, chicken scratch. Usually first letter of the word is 3-4 times bigger than the rest. People who can decipher this kind of handwriting are extremely rare. Those who write this way are more common.
-OK, this time I gave you B, but next time I see this EKG on your test I won't hesitate to give you F, no matter what you wrote. None of my colleagues could decipher what you wrote.
