<human>: Could you distill the essence of the text into 1-3 sentences?

We were talking about summer classes, which are notoriously hard. I was talking about how I can't do 12 hours next summer (2 classes in each mini semester) because they are hard. She had taken one summer class for her major (art, it was a upper level drawing class) and said summer classes are a breeze. I said my classes ( upper level business and management) will have more material to cover and that I've heard on every account that summer classes are not a breeze. She then said that I think my classes are harder to which I replied that there is more material to cover basically claiming that yes, they are harder. She is saying that she has worked very hard! I am very aware of that. I told her that I'm sorry for thinking her class was easier, that I don't think her degree is easier, and that I'm sorry if it came off like that.

She is upset with me and thinks that I don't think she works as hard and is taking an easy major. That I hold my self higher. I don't think any of this, I didn't put too much thought in what I was saying. 

What do I tell her to make her trust that I do in fact know she works just as hard as me?
<bot>: Made a stupid remark saying my business degree is harder than her art degree. I want to retract and her to believe me.
