I am trying to figure the correct way to answer the question:
授業をサボった時にどんな言い訳をよくしますか。
I want to say: "Usually I say i've been busy with my internship to the extend that I couldn't come to class"
which I wrote initially as:
授業に来られないほど忙しにインタンシップをしましたことをよく言います
but idk if 忙しに is the best form of saying an internship that had me busy...
