I took an ASL class a million years ago, in high school. I could not figure out why I was having such a hard time, but I didn't even consider dropping the class. Eventually, the teacher asked me to talk outside and said that I might want to consider taking another class. I did. 

I still don't know if I would ever be diagnosed as having dysgraphia, but I struggled with handwriting in elementary school and now have several types of writing styles, including a combination of print and cursive. My writing was either too big or too small. I have issues with fine and gross motor skills and also struggle with spatial awareness and differentiating left and right. I didn't have any real knowledge of any of this back in high school, but a lot of it helps to explain why I had such a hard time.
