I'm going to tell my date what I actually think of her degree
How do you feel about her degree?
It was shocking. I did not think she was going to get a degree.
It can be shocking to learn things about people as you start dating, but you should be careful about criticizing them in the start of the relationship. Otherwise it will end before it really begins.
It's not a big deal.
Well this can come across as a pretty disrespectful thing to say. If you are claiming that you did not think she was going to get a degree, you are making an inference based off of what you know about her. You basically mean that she does not seem intelligent or hard working enough to do this.
